Description:
The gammer talks to me to trade my unusual hats(Cloudy Moon Dr Dapper Topper and Sun Beam Gonzila) for 665 dollars.
I received that, and he had me give my hats first.
He invited to middleman in the chat and the middleman showed to me his rep(http://gyazo.com/b826f80c4222382f26ed6aa06263e39e)
But he is not real cream,he disguised cream and this is his real account(http://steamcommunity.com/id/255265265265/)(http://gyazo.com/364940c22794476dbab7ca752c40bcaf)
I watched that and trusted him,and I gave hats to him.
But after trading, he didn't reply anything.
There is my fault not to check gammer's rep.
Please take care you guys.

Both of them are already marked as scammers but I will add this to their rap sheets.
I highly recommend you go to http://support.steampowered.com and report this to them. They may be able to get you your hats back since there was actually no money involved and/or they may be able to trade ban these guys.
Thank you for the report!
