This account appears to have been used for fraudulent activity.

So my 15000$+ backpack is at risk here. My account has been restricted from doing an further accounts including trading. In a way it is a trade ban. https://gyazo.com/97a6f2308f3fd804fdf6c17500eb9a63

Story: A user sent me a trade offer stating him and his friends respected me and wanted to give me a gift. He was clean on SR, so I accepted it and in return I sent him back a key as a token of my appreciation.https://gyazo.com/baffac90318627b64471f5cf14ec4940 He then sent me another offer of his items for 32 keys claiming he needed tradable keys in which I accepted. At least one other user I know about has also been trade banned for trading with the suspected user. Most likely this Trade Ban was the result of the suspected user sending me a gift as it was the same case scenario as the other victim.https://gyazo.com/240cdbf1d04e26608b6a03f33a11a241 Well guys RIP me for now. Even if someone is nice enough to give you a gift, be careful who you receive it from. It may be seen as a scam. Am I permanently trade banned? Probably not (I hope). Discussing with Steam Support atm.

Can you explain where are you seeing that message?, I can't see you marked on SteamRep, bp.tf or Steam

Explanation that we have for this. We do not provide support or a platform to "tweak" with Valve's support. Hence this topic is archived.

The basic message is: Don't accept stuff from people you don't know.
