Description: This user randomly added me, asked me how much I wanted to get for the hat, used google translate as he is Russian, and failed miserably with the grammar and /me command (epic fail scammer)

Also, this user is multi-account (I'm assuming 5-7 accounts) of which he has added me with every one of them trying to buy my hat. He makes it very obvious he is linked to the accounts, such as all them adding me at once and asking for the hat.

I think this might be his main account:

I need help on this, it gets really annoying me having to waste my time on this guy for him to fail trying to scam me.

Also, heres a thread to his main accounts report ( http://forums.steamrep.com/threads/76561198049333079-leИin™.16118/ ), and in the comments I posted a month ago that his main account has added me and tried to scam me, along with several other accounts.

Hi there, please include your own steam information in the steam report or use the sign in with steam feature.It helps in identifying if you had contact with the person, as anybody could have just given you those screen shots.

Hello! Thank you for your report! An SR admin will investigate this in a while!
