If you say sites cannot be trusted, then why do you advise playing for fun after all playing for fun does not stop a player from committing money to get bankrolls?As a matter of fact, those who play for fun even spend more money on casino sites, because we all know the games are quite interesting and can be so addictive.
In my opinion, no one can recommend a site for a player except he does it himself, because what I want in a site might be different from what he needs. Do a quick search yourself and decide on what suits you. There are genuine sites and you can find so many of them on the forum.
You dont have to conceal an information regarding trusted sites because you feel its not necessary, someone is still in need of it either ways and this would not stop an interested player from digging further to know more about the site. I do research allot but at the same time I find it more comforting to hear the view of forum members on each site.
My advice remains that the best place to find reliable gambling site is still on the forum. I am convinced that whatever gambling sites advertised here are legit and methodically going outside here in search of trusted site is a risk no one would like to take.
