Feel free to ask.

If you lose the "Email" there is no way you can recover the account right ? so you need to create an account again and some casino are very welcome to bring back their customer. Off course with a condition like I said.

If a casino doesn't have a promotion.

The cheating is always like I said, want to get more amount to be betting for sportsbook user or abused the referral system by register under their link.
