I bought an unusual from a scammer, what do i do?

I saw this classfield on bp.tf for a half priced unusal (2.5-2.9 buds was selling for 22 keys), very eager to do the trade i added the guy and bought it for 20 keys. only after i traded for the unusual i saw he had a scammer tag and that he only had 0.1 hours on tf2. I know this was very obvious and i was very stupid, but i only had 1 unusual before and didn't think that the one selling an unusual would be a scammer alt. Should i just delete the unusual? I really have no clue and would like advice.

I also forgot to mention that after i asked to trade back for the unusual the keys were gone from his backpack.

who was it?

and no, there is no need to delete your item...

Someone by the name of MrRiks512 link to his profile - http://steamcommunity.com/profiles/76561198129294506.

What do i do with it? do i just keep it, am i allowed to sell it?

he's not a marked scammer. So no worries, and do with the item what you want. Just be careful with quick-sellers and "new" accounts etc.

Ok, thanks
