My account is more than 3 months old, and you are killing for unknown reasons. I figure out the reason and understand the problem. And I hope for a positive result.Maybe I broke something, but not intentionally. Sorry, please restore the account.
you said for "unknown reasons" but you "figure out the reason and understand the problem"
mind telling us what you were banned for? there should be a banned message on your account
if it was copy-paste/plagiarism, rest assured you won't get your account back
