Any place to report Key scams?

First trade ever on steam, and scammed by this guy:
| steamname: nosleep
| steamID32: STEAM_0:0:32928301
| steamID64: http://steamcommunity.com/profiles/76561198026122330
| customURL: http://steamcommunity.com/id/batmannnnn
| steamrep: http://steamrep.com/profiles/76561198026122330

Can't report it in the forum here, anywhere else I can do so?

Make a thread there.

OP is right, SteamRep does not take key scams.

Oh im sorry, my bad.

Thanks for your replies. So no place to report these? Obviously I can't prove it, but if 100 different people say someone is a key scammer...

You could always report him to steam support.

Contact Steam Support. It's the easiest way to physically ban him from trading and you might have a slight chance of getting your items recovered.
