Based on BPIP.org it's autoban I don't think mods or admin will ban your account when your account is hacked there is another reason why your account is currently banned.
I'm not saying that you know that the account is banned and pretending that your account is hacked but some of us think the same.

Usually, the auto ban will trigger when a user posts plagiarism do you try to check your account for possible plagiarism?
I think you better check the reasons why your account is banned it should be in your email or "My messages".
