I wouldn't trust this site.  From my post in a different thread: I registered for SWC last month through BTCgrinders rakeback offer of 15%.  BTCgrinders shows that I'm being properly tracked on the site, and I've played quite a bit of NL cash game and NL tournament while dabbling in some short deck, PLO, OFC and other games occasionally.  Did not see my BTCgrinders account being credited with any rakeback.  Emailed their support 3 weeks ago, then again last week, and again this week about rakeback being credited to me.  No reply from them at any point.  Is it too early to call this site a scam?
