Hey @stillkoy,
You should have received an email at the time of the initial ban letting you know the reason for the ban.
If you're able to check back through your registered account email for anything from a [email protected] address or @ea.com domain that should provide a bit more clarity for the reason that action was taken.
We are unable to discuss any account details on the forums I'm afraid, so if you've already exhausted multiple appeals and the Terms of Service team has declined to remove the ban from your account, that is not something we'll be able to change either, sorry.
