Back in the day a RTG casino refused to pay my winning of 2K because I had a multiple accounts with them. I believe those 2 casinos are blacklisted so we are aware of them and try to avoid them. Actually Bovada said I was abusing the bonus by withdrawing and re-depositing, when in fact I NEVER EVEN RECEIVED MY WITHDRAWAL!!! The next day both sites emailed me that they needed to verify my account. This time I deposited $1k the first three times and lost. I was so hyped about my win and googled other casino bonuses.
