Your scam accusation can be easily supported by the community if there’s an obvious scam happened. Assuming that your concerned is, Blackjack.fun is already willing to compensate to the potential damage for the “bug” that you discovered even though they don’t have bug bounty program.

The problem here is only “YOU” have concern on this bug while the rest of the player on that casino doesn’t bother at all even though they have more play time there than you. Maybe find other victim to support your accusation.
