I've been trying to appeal some of my earlier accounts that were perm bans but to no success, obviously there are some exceptions to people's luck on getting unbanned but in your case, I see it as your account is basically screwed and there's little to no chance of getting it back, but that would probably depend on your account progression. You were temp banned once and you didn't learn so in theory you shouldn't be given a third chance at coming back. Though, you should always give it a try and if they don't accept, just give it up.
