I believe it's a scam. I tried and tested it for a while but never got my withdraw from there. Shame, it could have been fun concept.
Not a scam. Still the activity sets doubts...
I have withdrawn from there 16 times with no prob. But at 17th attempt suddenly I got account suspended, with no reasonable cause, since my case does not fall into the reason given. I do not block ads.
After 48 hours my account suspension was lifted but I do not know who else has been reinstated.
But other players have been suspended for longer than a week before announce was published, and yet they dont know if they will get account "rescued"
The events at the website are in many cases very surprising... so say it softly ...
