I can't speak for everyone and won't try too, but personally the only 2 sites I even have confidence in right now are BCP/ACR and Bovada. Lock/Juicy is basically play money, Carbon is still somewhat legitimate so I don't think you should cut them down too much since people seem to still like playing there, but I play primarily on BCP and have for a year now, and won't even consider wasting my time with a $10 freeroll on there, even if I have zero in my account. Raise BCP to at least $30! My two cents..
