I don't know why you want to be temporarily blocked just because of your gambling habits and request to be unbanned after a certain period. I haven't seen anyone make such request before and I'm not sure if it is possible.
That's the reason why a self-exclusion is available in any gambling website and is required to any licensed casino, for responsible gambling.
In this case of OP, idk what to say since he is partly to blame here, and it's actually avoidable if he chose not to play on that time he "requested" for self-exclusion without getting approved. And i don't think 1xbit will care knowing they are known as scam and will just wash their hands and will put the blame to OP.
