Are you sure you did not violated the terms of service on some way? What would make more sense than telling you that you are addicted and need to stop.
Rare to see, especially if we not doing anything.
Casino will never ever cut off their milk procedure (which mean they customer). There has two reason for these case:
1. We request self exclusion but in these case seem like he not doing it
2. Could be, he somehow mad and chat somethings to "Stake Support or Someone Work" in Stake multiple time like bad things stuff and other. Then, they're taking conclusion he was an addict and decide to closed his account.
I seeing case no.2 in "BossManJack" cause he getting sponsor by Stake and he saying Stake was rigged and other for the game. Finally they gave him some pause or closed the account due several reason addiction gambling and not just thats he was in high coke as well.
