also I just asked for payment looking in google and I just found the post here at bitcointalk I hope this website pays 
So far there is no complains about payment, some people even confirmed that they receive their withdrawal from this site so I guess it is safe enough. The only complain is about the lack of real players, most of the players are just bots.
The maximum number of real players playing simultaneously on this site was 6 if I'm not mistaken. But it is not so rare to see 2-3 human players at different tables. Yesterday, for example, three players, Gennady, Here4Trades and one other were playing NL Hold'em at 100/200 table without bots. I didn't join because I play poker poorly but it was nice to watch. Btw it's interesting for me to know who won eventually.
