What you're failing to understand is we do not have a decision in this matter; once we were made aware that this account was owned by someone in Iran, we had no choice but to cease activity immediately under current US Law due to the US sanctions against Iran, and the way cPanel interprets those sanctions. This also means we are not able to provide backups, however that is due to our requirement to enforce our Terms of Service equally - if we provide backups in this situation, we must also do so for account suspended for phishing, warez, and every other ToS violation available as this account did indeed violate our Terms of Service (it violates US Federal regulations by existing unfortunately). We simply cannot do this, as we do have a strict zero tolerance policy that is outlined in sections 6 and 8 of the Terms of Service.
As far as searching the .ir domains goes, that has already been done; you weren't the only user identified in this manner, and all were suspended.
As there's nothing we can do to provide backups or restore the account in any way, I am closing this ticket - your dispute has already been reviewed as well, and unfortunately there is no way to bypass this situation due to the nature of the violation.
