As you wrote, it's best to wait for the support response.
After all, there are many reasons for closing an account, and you can violate the rules in many ways.
In another post, I gave an example of how it happens that users even unknowingly violate the rules by using a VPN built into the Opera browser.
We don't know what caused this account to be closed, so let's wait for the support's reaction.
Let me guess they have deleted the user's account because of the violations but they will not specify what kind of violations, they keep banning account without specifying the rules that were broken or if they specify it, users will deny it because it's all lies.
I have a good guess because the scam sections are full of 1XBIT accusations, they are almost the same, and are you one of the staff of 1XBIT you are in a hurry to defend 1XBIT, you're part of the signature campaign don't act like you are one of the staff.
