Unknown Negative Feedback for No Reason

This isn't Steamtrades, and has nothing to do with it apart from having a link to that site.

You use Steamtrades at your own risk.

this is not the place to ask for help.

Sometimes you're blessed with a false REP on Steamtrades. Maybe other users will remove the false -rep, but it can take a while.

I get that you are frustrated, but what kind of help do you expect from simple vanilla users in a site-related issue?

It is pretty common for scammers to impersonate other Steam users. The user may have been scammed by someone that copied your username and image and now the user thinks you are the person they traded with.

As far as I know Steamtrades is abandoned and won't be further developed, nor do mods do anything about what happens on that site anymore. However if that really is the case then they should remove the "Misuse of trade feedback" from support tickets, instead of allowing them just to close them without actually doing anything about it.

Anyway, like some people here pointed out other ST users can review negative feedback and vote whether it should stay or be removed from profiles. When it comes to that system however, let me say that having a private steam profile doesn't help your case.

Tell the user that gave you negative rep to check their trade history and see which account they actually did trade with; then report that account to Steam. Not like that's gonna do much, but at least there will be one more educated user (check who you're trading with!) and they'll stop blaming you :)

Thanks for everyone's help!
