I did play this 24/7. only thing which i didn't do is playing it in a real poker table. I have played it in poker stars/888 for money. have to say there are people organized and sitting a in table just to grab the money from amateurs.(in 5 seater table there 3-4 people, could be the same person or group of people who knows each other.those sites do allow to use multiple sessions from same IP) it is really hard to win there unless you possess extreme patients.
I don't think poker stars and 888 poker have been fixed. still it is very hard to win there. So no point in spending money to play poker there with real money. no gain,
