社区交易提示 是一组给予新步入军团要塞2的Steam交易

物品价值

通常来说，物品的价值取决于稀有度，也就是说，玩家能获得该物品的难度和付出的代价。由此引申，物品的稀有度通常于物品的品质有关联。因此，游戏中最容易掉落的独特武器，也有有着游戏中最低的价值，毕竟很容易掉落，而且还可以合成。有一些独特武器可能因为其等级或合成数字有着独特的价值(等级比如43，69或100；合成数字从1到100)。曼恩公司供应箱是长时掉落的物品，价值甚至会比独特武器还要低。特等物品则因为它们本来就有着更高的合成价值，加上现在无法通过一般途径制造出来，因此价值比较高。奇异物品是通过开箱获得，因此比独特武器有着更高的价值，但它们的价格还取决于许多因素，比如部分武器只能从特定箱子开出，武器的受欢迎度等等。纯正物品则比上述的品质物品的价值都要高，因为它们通常都是些促销物品，想要获得它们都是有时间限制的。

闹鬼物品也是高价值的，它们只能在万圣节活动和地图中获得。节日武器有着相似的季节限制，但它们价格可更高，因为这些物品只能在圣诞节活动时的开启的补给箱获得，而且不同的箱子也能开出不同的物品，更别说节日武器还很好看。而节日奇异武器则有着更加高的价值。但是，节日化武器则不同，它们是与节日武器所区分开的。节日化武器是使用工具给武器加上了节日化的属性，使其类似于节日武器，但是这毕竟是使用道具加工的物品，比起原来原始的节日武器，节日化武器的价值就不如节日武器。

某些物品，例如曼恩公司供应箱钥匙通过供求关系的概念而计入账号的价值。

有着特定品质或设定的物品则被称为"脏"物品，包括有着("授勋于__")，使用名称标签或描述标签改变了物品的属性，需要包装礼物的和不能参与合成的，或者是有着任何种类的交易限制的物品都计入脏物品。脏物品一般都比"干净"的物品的价值要低。

物品被工具添加过属性的，比如使用了油漆桶或奇异升级部件的物品，通常会在交易中给物品添加价值。

货币

金属是交易者们常用的货币，用于交换对应价值的物品。物品的价格单位一般叫做精炼金属，或者说是"ref"(例如 1.33 ref, 3 ref ) 。对应的每一种金属的价值如下：1残留金属=0.11ref；1再生金属(或者叫做rec)=0.33ref，1精炼金属=1ref。因为一个残留金属是从两个武器合成的，每一个独特武器可以被认为0.05ref。但是，有时候可以见到用1个残留金属交易独特武器的情况。

对于高价值的物品，高等级的"货币"就上场了。钥匙就是下一个阶段使用的货币，不过同等量价值的金属也常常可以当作钥匙货币使用。耳机，也就是常说的"Buds"也是在高价交易中常用的货币。不过一个热门的交易网站Backpack.tf在2015年3月31日发表声明buds不会再被用于TF2交易的货币。

有时，交易者会用饰品对于缺少金属或钥匙的情况下进行补偿。这就是我们说的overpay。这个方法很少人使用。使用帽子交易帽子的行为还是在你的好友之间进行会比较轻松。

澳元素武器

Australium weapons are only obtainable in the PvE game mode Mann vs. Machine with a Tour of Duty Ticket. These weapons appear to be coated with a gold-like substance, Australium. They are obtained only as strange weapons to count kills. The probability of getting an item like this from Mann vs. Machine is normally 3% - 4%. They are considered a valuable and expensive type of items for trade right next to Unusual Items. For the list of available Australium weapons, see the main article.

The Golden Wrench, Saxxy, and Golden Frying Pan are exceptionally rare Australium-colored weapons different from the Australium weapons above. The Golden Wrench and Saxxy are untradable. The Golden Frying Pan is a particularly rare drop in Mann Up mode, obtainable only in a 0.025%^{[需要来源链接]} chance for completing the Operation Two Cities Tour of Duty in Mann Up mode, taking about four advanced MvM missions to complete.

稀有物品

Unusual items are considered to be the most valuable and expensive quality for trade in the game by a wide margin. As such, they are considered to be in their own separate tier of high prices (usually given in keys). In addition to the visual appeal of the Unusual Effects these items sport a 1% probability of being acquired from Crates , making them extremely hard to come by, and making their base trading price extremely high. However, within its own realm of Unusual prices, the value of an Unusual item may vary wildly according to visual or thematic appeal, rarity, and general desirability.

交易提示

When trading for a Strange or Unusual item, look out for the quality colors to avoid being scammed. Note that the Free to Play account cannot give any items in the trade unless they are items that have been given to them through trading in the past.

Keep the following tips in mind while trading:

• To know how much metal is being asked for an item, keep in mind the specific values for each type of metal: 1 Scrap Metal is 0.11 refined (or simply scrap), 1 Reclaimed Metal (or rec) is 0.33 ref and 1 Refined Metal is 1 ref. Adding these values by increments will give you the exact value of metal that a trader is asking for, and lets you know which and how many items of metal are being asked of you.
• Check the person's Steam profile to see if the person is on trade probation by Valve, or has a reputation for being a scammer. Also use SteamRep.
• Use a trusted SteamRep middleman when doing cash trades.
• Always review the items being traded before finishing the trade.
• Trades should be conducted without any pressure; don't give into another player's pressure if they're urging you into a trade you do not want to be in.
• Always have an ideal price for every item you trade to prevent unfair exchanges. You can find out using price guided websites.
• If you feel that you are offering too much, ask a friend or another player. There are many "price guides" available online that estimate the value of items being traded (though these are often subjective).
• Inventory items appear in the order in which they are arranged in your backpack. Be sure to preview items by hovering over them in the inventory or trading boxes to make sure you are adding the correct one(s).
• Always respect the player you are trading with. Being polite, courteous and honest are very important aspects of trading, and are reflected on in real life trading too. Common courtesy is an important aspect.
• Be aware of renamed items, as a scammer can rename a common item to appear as to be an item of a higher quality. For example, a Vintage Pyro's Beanie can be renamed to appear as an Unusual Pyro's Beanie. However, the cosmetic will retain its blue lettering. The chat box will show notifications about renamed items to help avoid confusion. Hovering over the item will also show it's original name before it was renamed.
• Check if the items you receive in the trade are gifted or uncraftable, as they are generally valued lower than the non-gifted or craftable equivalent.
• Make sure the items you are receiving are not duplicated (or duped for short); you can check this by viewing a player's backpack on backpack.tf, and by checking the item history of the item. Most items (especially those of an Unusual quality) hold a lower value if it is a duplicate of the original item so be wary.
• If you are trading for a strange weapon, its current kill count will be reset to 0 once you receive the item.
• While trading, verify the trader's last alias (This user has also played as) at his profile. Scamming players often use many different aliases, so they can't be recognized after the trade.
• Some trading communities have adopted a verify system that can be very useful to the traders. If your trading spot has it, be aware of it.

交易种类

There are several different types of trading:

• Scrap banking - an act where a player charges metal for weapons. Scrap bankers will usually exchange one scrap for two weapons initially, and then charge one scrap for one weapon after banking them, gaining them a small profit. This can also be performed the other way around, by trading two weapons to a scrap banker. This is referred to as reverse scrap banking.
• Weapon banking - an act where a player gives another player a weapon for another weapon.
• Cosmetic banking - an act where a player purchases Cosmetic for 1.33 refined (the general price for the majority of craftable cosmetics) or lower, then sells them for 1.33 refined or more, gaining the player a profit.
• Key Banking - an act where a player exchanges their Mann Co. Supply Crate Keys for metal, mainly refined metal.
• 1:1 trading - an act where a player exchanges a single item with another player for another item.
• Item overpay - Overpaying for an item by .11 (1 scrap) to 1 key in items compared to the required amount for the other player's item(s)
• Game trading - involves exchanging items for games and vice versa.
• Cash trading - involves exchanging items for monetary compensation outside of the Steam trade. This form of trading should always be done with a trusted middleman, if done at all; this practice is very risky, and is not supported by Valve.
• Pure trading - when a person pays the pure value for a specified item, generally in Refined or Keys.
• Quicksell trading - when a person sells an item (often with the Unusual quality) for pure currency for a value that is less than the suggested price of their item.
• Bot trading - when a player goes to a website that have steam accounts that collect items in order to trade them to real players, these websites often have the same banking as said previously, for example weapons can have: buy weapons, sell weapons, auto sell (sells all duplicate weapons for scrap), auto buy (buys all weapons it registers that you don't have), the trade sites often require you to have your inventory open so it can see your weapons and other items. Some bot sites still require a lot of work to make perfect, so if you use a bot site, always look on the trade one more time. An example on a bot site is scrap.tf.

Things that should be watched out for:

• Scamming - the act of stealing from another person, generally when a player promises another player items that they will never give.
• Phishing/Hijacking - when a user pretending to be a trader sends a phishing link (which redirects the player to a fake site that harvests their login details or other information), or asks for a player's password. Players should always check the name of the link they are clicking and check for a green bar at the top of their browser signifying security. They should never share their password with anyone.
• Sharking - the act of targeting a player (usually new or inexperienced players/traders) and offering items that are worth a significant amount less than the targeted player's item(s) while telling them that they are worth the same amount.

交易之前

• Ascertain the value of the items you want to trade. Always try to figure out what your items are worth before trading them. See Item Value for more information.

• Check if the person you are trading with is a legitimate trader and is who they say they are. Check the person’s Steam profile yourself (do not click any links) and/or their SteamRep page. Their SteamRep profile will also display if the person has a Valve trade ban or Valve trade probation. (For other ways to verify, see Reputation below.)

• Do NOT click on any links to external websites as these sites could be malicious and/or phishing sites.

• If cash trades are involved, make sure that you secure a verified community middleman.

• Do NOT use TeamViewer or any other software that the other user tells you to install or use.

• Do NOT believe anyone who says that they are from Steam Support. Steam Support will NEVER ask you to trade items to them for any reason.

• Steam Wallet Funds can not be traded. Any trades offers that state that Steam Wallet Funds will be added after the trade are scams.

交易途中

• Click on the name of the other person while in the trade window to verify that is the real person and not an impersonator.

• Do NOT click on any links the person sends you in the trade chat window or run any programs the person asks you to run while in the trade.

• Pay close attention to the trade. Check the trade chat to ensure that no items were removed. Make certain all agreed items are visible in the window before accepting the trade. If you cannot see an item, cancel the trade.

• Pay attention to the quality of the items being offered. Take your time to verify all items by hovering over them to ensure it is exactly the item you agreed to get.

• Be aware of renamed items, as a scammer can rename a common item to appear as a rare item. Double-check the quality, names, and descriptions of all items. Items which are renamed or have had their description changed will have quotation marks (“) around the name and description. The chat box will also show notifications about renamed items to help avoid confusion.

• Inventory items appear in the order in which they are arranged in your backpack. Be sure to preview items by hovering over them in the inventory or trading boxes to make sure you are adding the correct one(s).

• Check if the items you receive in the trade are craftable. After the October 13, 2011 patch, weapons bought from the store are uncraftable, but can be traded. After the November 29, 2012 patch, cosmetic items bought from the store are craftable.

• Common courtesy is important. Always treat other players with respect.

• Do NOT rush the trade. Give yourself plenty of time to review and verify all items before completing the trade- especially after the green box is checked but before the final trade button is pressed.

• You should always have a bit of control over the trade. You should never be pressured to sell your item at an discounted price. If you ever feel uncomfortable, do not hesitate to cancel the trade.

• Never be afraid to check item history. If an item is duplicated, which will appear in the item history, it is not recommended to buy that item. This is because they are much less desirable on the market, and it will be harder to sell (unless you plan on keeping that specific item for yourself).

什么不该交易

• Do NOT trade for CD keys or games that cannot be traded through the trading window.

• Do NOT trade Steam accounts. The buying, selling, sharing, or trading of Steam accounts violates the Steam Subscriber Agreement.

• Do NOT trade for items in other platforms, such as for Runescape gold, Minecraft accounts, etc.

信誉

Reputation is often used in the trading community especially in the realm of cash trading. Red Flags:

• New account (if the account that the person is on is relatively new, they could be using an alternate account)

• Low TF2 hours (if the person has only 100 or so hours in TF2, but they want to trade for a high value item, it could be a fishy situation)

• Low amount of games in their library, or only free to play games. People who have no attachment to their accounts (alternatives) often have almost no games in their account, or only free to play games. (This way if they lose their account they don't lose any games)

其他提示

• To know how much metal is being asked for an item, keep in mind the specific values for each type of metal:
  • 1 Scrap Metal is 0.11 Refined Metal (ref)
  • 1 Reclaimed Metal (rec) is 0.33 ref
  • 1 Refined Metal (ref) is 1 ref.
  • 1 Key consistently fluctuates in price (refined, that is,) use backpack.tf if you want to check the current key:refined ratio.

Adding these values by increments will give you the exact value of metal that a trader is asking for, and lets you know which and how many items of metal are being asked of you.

• Make sure the items you are receiving are not duplicated. Duplicated items may not be legitimate and/or are worth considerably less than non-duplicated items.
• If you are trading for a strange weapon, its current kill count will be reset to 0.
• While trading, verify the trader's last alias (this user has also played as) on his profile. Scamming players often use many different aliases so they can't be recognized after the trade.
• Some trading communities have adopted a verify system that can be very useful to the traders. If your trading community has it, be aware of it.
• Also use backpack.tf to search the price of items you want and check price of your backpack. You can also check prices of marketable items on the Steam Community Market.

交易诈骗

Scammers are users that attempt to steal other people's items by deceptive means. They do this in three different ways:

• Convincing the victim to trade them items while receiving nothing in return
• Misleading the victim on how valuable certain items are, and knowingly offering an unfair trade(this is called sharking)
• Convincing the victim to click on a corrupted link, which allows the scammer to hijack the victim's account and/or trade offers sent to other people.

Thus, as long as you never give items to strangers for free, never click on suspicious links, and always know the true value of both your items and theirs, you have nothing to fear from scammers.

There are many different scamming strategies. All known methods are listed down below:

移花接木诈骗

This method is extremely ineffective now with the trade hold and additional verification. Once both parties have agreed upon a fair trade and they are happy, the scammer instead offers a similar item of less value, and hopes that the victim won't notice the difference. Fortunately, this method is much harder to pull off now because extra verification is needed before the trade can be completed giving the victim an extra chance to notice.

假机器人诈骗

A screenshot of a fake Opskins bot scam

This is a type of impersonation scam. Fake bots are accounts that send you offers for items in exchange for nothing, usually to 'deposit' them into a site, which after being deposited, cannot be withdrawn. The Scam usually goes like this:

• A Scammer adds a user to their friend list
• they lead the user to a well-known trading site (e.g., Opskins, Marketplace.tf, etc.) (or they can lead you to a fake trading site made just for scamming)
• they get the user to list their item but not deposit it
• a fake bot sends the user an offer for your item for nothing in return
• the scammer tries to convince the user to accept the trade
• once the user accepts, the scammer blocks the user and the deposited items cannot be withdrawn.

假中间人诈骗

This is another type of impersonation scam. Some traders use middlemen to be a mediator when trading highly valuable items to make sure the items go to the right people and prevent most types of scams. However, middlemen can be impersonated and take the valuable items without giving it to the respective users. A lot of the time the fake middleman will be working with/be an alt account of a scammer to take your items. It will usually go down like this:

• You have a valuable item that you wish to trade.
• You meet with someone who is willing to trade and they insist on getting a middleman.
• The middleman and the person you are trading with are friends or the middleman is an alt of the scammer.
• The middleman takes all the items and gives it to the scammer.

or it can go down like this:

• You are trading valuable items and you want to get a middleman involved.
• The other user agrees and you trade your items to the middleman.
• The middleman takes the items and leaves.
• The middleman will most likely block you.

钓鱼链接诈骗

Phishing links are links to websites usually impersonating Steam or other well-known websites and require you to sign in to steal your account credentials, and hijack your account. In some occasions simply accessing the website may download malware and do harm to your computer and potentially steal your personal information.

Examining and not clicking on suspicious links will prevent you from getting affected by this type of scam.

好友诈骗

This is another type of impersonation scam. The scammer will ask you to trade your items to a trusted friend of yours who the scammer will impersonate to decieve you to trade the items to the fake account. It usually goes like this:

• The scammer adds the victim.
• The scammer and the victim agree on a deal for a trade.
• The scammer says to make sure the promised items are 'legit' that the user has to temporarily trade it to a friend they trust, then they can complete the trade.
• The scammer's alt/friend impersonates the friend you said you would lend your promised items too.
• You give your promised items to the scammer's alt/friend not realizing its not your real friend.
• The scammer and the fake account block you and the items are scammed off of you.

假主播诈骗

This is another type of impersonation scam. An account impersonating a popular YouTuber/streamer will add you, and tell you that they need your items for a showcase video. Once you have given your items to them, they block you. Checking the YouTuber/streamer's actual Steam profile can help you identify if it's a scammer, as the "Add Friend" button should change to "Send Message" if you are already their friend. Also checking the scammer's inventory to see if it is private can help.

黑箱子诈骗

In this particular scam, a scammer adds a user to their friend list, they tell the user that their crates in their inventory are hacked and that they will 100% unbox a Unusual when opened. The user pays the scammer for the crates unboxes them and gets nothing (although there is the normal small chance they could get an expensive item) and realizes that the scammer was lying when he said the crates were hacked and that they were just normal crates.

虚价

Sharking is a type of scam in which the scammer tells the victim that the scammer's item is worth far more than it actually is, or that the victim's item is worth far less than it actually is. This is largely preventable through referencing websites like backpack.tf, or by checking the Steam Community Market prices if the items are marketable, as these give community-decided values of the items in question.

假的Valve雇员

This is another type of impersonation scam. The scammer will impersonate a Valve employee (e.g. Robin Walker, Drunken F00l), and will proceed to ask you to trade your items to them for various reasons. Note that Valve employees will never contact you personally for your items, even if they are glitched.

节日/节日化

This scam is more recent than others, as in the Smissmas 2017 Update Valve updated Festivizers to be able to Festivize more weapons than previously (including Stock weapons). The scammer sends you a trade offer proclaiming the item to be an original Festive weapon or Strange Festive, thus upping the item's worth. (Example: you have a 12 Key item, you list it for that price, you get an offer for a Strange "Festive" Scattergun, when you hover over the item it shows as Festivized.) Note that original Festive weapons have a different backpack icon than Festivized weapons, use this to distinguish whether it is a Original Festive or a Festivized one.

物品乐透诈骗

This scam involves a TF2 gambling website that the scammer supposedly runs. Some of these websites fake the entire process. Typically, a scammer adds a TF2 player over steam to their friends list. If the TF2 player accepts, the scammer asks the player to advertise their item roulette website and promises to "fix" (guarantee the TF2 player to win a round) some roulette rounds in exchange for their help. Alternatively, a scammer may "fix" a round so that a select roulette player (which sometimes may be a fake player/bot) of the would-be victim's choosing is guaranteed to win as proof to the would-be victim that the scammer is in fact capable of "fixing" rounds. Items can be scammed from a would-be victim in three ways:

• Sometimes a "fee" is required to play the roulette game in the first place.
• By entering the game, a would-be victim's items are simply pocketed by the scammers involved and are never actually given to a "winner" (sometimes fake players or bots pretend to be a would-be winner).
• Even if the roulette round is legitimate, rounds can be "fixed" and unfairly manipulated to guarantee a winner (which is often done to lure in new would-be victims).

In addition, this scam can easily become widespread due to scammers requiring victims to advertise these roulette or gambling sites in order to attract new would-be victims.

其他游戏/Abstractism假物品诈骗

来自游戏Abstractism的假物品截图

这是一种新形式的诈骗。Abstractism是一款使用了军团要塞2游戏物品图标作为库存物品的游戏，它因代码侵权，恶意内容与欺骗消费者等多项指控而于2018年7月30日被Steam 商店下架。
骗子会声称他们有昂贵的物品（比如澳元素武器，稀有饰品等），有时候也会先展示真物品以取得信任，随后在交易中使用这类假物品进行诈骗，且这类假物品有时能以假乱真，难以分辨。。
然而一些假物品并没有军团要塞2的图标，你可以使用这个技巧来分辨它是不是来自另一游戏的假物品。
此外Valve还追加了额外防护措施，比如在交易窗口警告某件物品所属的游戏是最近才被添加到Steam商店的，或者该物品所属的游戏并不是用户常玩的，这些警告也能够帮助用户分辨物品的真假。
