Scammed me, (I knew I should have walked, but wanted to trade) but I was careful so didn't lose too much...
Stupid me just closed his chat window though... anyway, he got a worms golf key off me, from gala 9, I still have rest...
For reference he sent me this after:
saw yesterday someone report someone else posting this at the end, so same person me guess.
Am slowly reporting him to steam and steam rep, any help in doing so is appreciated!
He said this guy could vouch for him, also said i could talk to him (didn't though): http://steamcommunity.com/profiles/76561198020436242 Phil_8811, so I guess? that is his main account?

Unfortunately there isn't enough evidence to process this report. We absolutely need chat logs or any evidence confirming that this scam occurred.
