Why are you deleting your posts? If you delete them for not spamming, you'll still don't got unbanned.
Do you think I'm dumb or something, I'm not doing it for getting unbanned just some posts I had to delete. And if you don't have anything useful to contribute here you are free to go
As what I know, banned accounts (and previous SCAMMER accounts) aren't allowed to delete posts. If you really want your posts to be deleted, you may report them to moderator (myself have deleted old bumps in auction board where posts can't deleted) one by one. If they know your situation, they may delete them for you.
