There is still a campaign on this forum that you can use the site for exchanging coins anonymously even with tor or VPN but not banned because it does not go against the rules of this forum. Mixers are the threat and it is about converting bitcoin to bitcoin on those centralized mixers that were banned on this forum.
You're not totally correct bruh 
People are all out, looking for the slightest means to bypass the privacy ban/censorships. It's possible that they'd take an advantage of a casino that doesn't require KYCs, depositing dirty coins and withdrawing clean ones.. The forum isn't against casinos that don't have KYC options, it's against casinos that allow users to swap thier coins for either a coin of same value, or another altcoin.
