in my social media group, I met someone who was selling a casino account, one of the biggest on this forum. surely an account that has KYC and a decent monthly bonus makes a casino account valuable.
The casino clearly prohibits this, if detected by the casino the account will definitely be banned. especially with Casio which initially did not require KYC, after their regulations required KYC, maybe some people have several casino accounts that are operated by themselves.
If they only sell to the same nationally citizen, I think it will be hard for the casino to spot the account was changed hands.
The casino can detect difference of IP address and the account was never connect to the old IP address, but the new owner can give excuse like they've moved to new country. Any VIP account already have submitted KYC, even though the casino can request again in the future.
