If there's a gambling website which accepts Bitcoin they HAVE TO open an announcement & support thread in Bitcointalk. Look I don't say they "should" but they "HAVE TO". Otherwise that site is %99 scam and I wouldn't play in that site.
Sometimes websites with topics on bitcointalk can be scams...
Thats why before you do some deposit in it you should check the reviews from other people. This is an active thread, many people will leave the comment before you do it so you will know this is a scam or not
