In my opinion if Sportsbet explain how user neymarjr12 has multi-accounts then they might compromise their algorithm so for me that is something they should not necessarily make public.

As for the KYC failing, I think they should have explained to neymarjr12 exactly why it failed their checks and then it was up to neymarjr12 to explain why it failed because Sportsbet are falling under UK data protection laws and also European GDPR therefore they should not make any information public but give as much as they can to neymarjr12 then let him make it public.

Even with all the discussion that has taken place in this thread I cannot support the flags for reasons stated here: https://bitcointalk.org/index.php?topic=5263445.msg54893685#msg54893685

The only issue I have with Sportsbet is the fact they allow deposits to take place and allow bets to take place even though their algorithm flags the user - by this I can only conclude Sportsbet are happy to keep the funds if the user loses. The problem arises when the user wins and maybe wins big, then Sportsbet can go through the history of the user account and show total funds deposited vs total amount won and then use any amount they want to settle the issue by saying they have a right to withhold winnings. Though that might be true it is morally incorrect if they allow users they deem to be fraudsters to deposit money.

Sportsbet are not the only casino to operate like this, too many casinos do it and it is a practice that really needs to change. Too many exchanges are doing the same thing but using KYC or other excuses to freeze funds.
