Well, you've clearly been banned.
He's not banned for breaking forum rules, his account is locked.
yes, the account is locked, it's been inactive for almost 2 years according to bpip
but something fishy is going on, there are too many password changes/resets within the last week
and he just did password reset via security question, which triggers locking
so it's either the long inactivity or password reset gets his account locked
