If I am not mistaken, on your previous case with maverick, you mentioned that you traveled a lot and uses VPN, which could contribute to some other account [that is not belonged to you] to be linked to you if you use free VPN, though the possibility is somewhat small, given Rollbit usually matched several datapoints to be sure with their findings of multi-acc abuse prior to locking the account.

I have another theory about sportsbook limitation in my head, I think similar situation [regarding sportsbook] happened in the past, but it's a whole another level of mess I'm currently not interested to dive myself into, so I'll keep that theory for myself for the time being.

I am notifying Razer about this.
