Yeah, This is dangerous for those user that selling there verified gambling account in the market. I saw many users before that selling this kind of accounts and most probably it was hacked account. Worst scenario was your KYC account got hacked and used to cheat in the casino while you have the ID for the casino to trace and sue you for the violations that scammer did. This is what I’m avoiding too on submitting my KYC on casino.
Due to hacked accounts and fraudulent users, the casinos themselves suffer. After all, if a player has conceived fraud, then even despite the presence of KYC, he will use a fraudulent or hacked account.
