this is a scammer stay away after i was offered on forums to play at blizz.io i deposited and won then i asked to withdraw they asked me to verify my identity after i sent the documents for verification they closed my account and took all my money for a very absurd reason i really don't understand what is going on
this is the reason they give really I don't know anything they don't have any proof

Who offered you to play there? because it's impossible for it to appear because you saw the thread from the casino because this casino thread has been inactive for a long time so it has been deeply embedded, unless you get an offer to play at the casino the very first time they appear on this forum and that means you have been playing there long enough.
Like some of the suggestions above, first move this thread to the
Scam Accusations even though many member see this as just a complaint from a player who was detected cheating, but you won't get any answer from the casino representative so filing a complaint on askgambler is another option. But no matter what steps you take if they do find fraud it will not make you successful in taking your money even if you deny it.
