Hey @Zalar01HU,
If you're relying on the account ban history page to say that you're not suspended, do keep in mind that it notes there are certain bans or suspensions that do not appear on that page.
If you're seeing a banned message in-game, there is indeed an account action not showing up on that page.
I'd definitely suggest going through these security steps to make sure no one else may have access to the account, and reaching out to an advisor so they can help re-secure the account as well.
An advisor should be able to help appeal that ban with our Terms of Service team afterwards, or you can create the appeal yourself if you've already taken steps to re-secure the account.
The ToS team will review the action preventing you from playing and will reach back out via email as soon as that investigation is complete.
