Are these sites, as they say?
Please contribute.
888 is a publicly traded company and responsible to share holders. They probably spend a lot of money on security for the above reason. They are huge as gambling sites go. They also used to spam alot but not so much these days, they seem to be getting their act together. They have a casino representative you can contact named Racheal888 at the casinomeister forum and she always sorts any issues out very quickly. Overall they should be very secure. Famous last words ;D
