I used to play tournaments, NLHE and PLO but would only play freerolls now due to their software having repeated security issues and the super user scandal a while back, they obviously don't really give a **** about their customers.
yeah i used to play on fulltilt, titan poker, pokerstars etc but gave up on all of them. pokerstars probly has the best freerolls going if they still do them. got sick of having 6+ lots of poker installed on my laptop tho so cut it back down to one lol. and UB was the one i first tried so i find it the most comfortable to use
