Dealing with impersonators/scammers

Hi Guys.

I am a Moderator on the gamling website CSGOBIG and i have a few problems. People tend to impersonate me and try and scam our users, anyone have ideas on what can i do to prevent that?

On my steam profile ( https://steamcommunity.com/id/DPGHYPE ) i have a list of known impersonators, and i also reported everyone to steam, but nothing really more i can do i think. But wanted to ask you guys, if you had any ideas.

Example, right now (in these hours) theres a guy (a well known scammer mostly going under the name Seiya), who has a profile who looks like mine ( http://steamcommunity.com/profiles/76561198114288319 ), even have fake steamrep photoshopped pictures, who's adding users and trying to scam them posing as me. Of cause i warned the users about him, but really.. i feel bad for the people who fall for it, when its not really me.
