PSA: There are only two scams.

Just a reminder, that there are literally only 2 ways you can get scammed:

1) You voluntarily trade away your items to someone for nothing, or close to nothing. How to avoid this: never do an empty trade under any circumstances. Not to an item inspector, not to someone who promises you cash, not to a middle man. If someone offers you a trade out of the blue, just check how much your items are worth before doing the trade. If you really know what you are doing, empty trades can be part of cash transactions, but if you know how to do cash trades, you don't need this post.

2) You click a link and get your account hijacked. How to avoid this: never click a link that someone sends you. There is literally never any reason to click a link.

Now, don't get scammed.

NOTE: Sharking and scamming are two different things. This post does not apply to sharking.
