You probably got banned for breaking rule 1,
No zero or low value, pointless or uninteresting posts or threads.
due to all the generic one-liners you posted.
(Don't quote me on this though, it could be that you copy-pasted content aswell.)
As far as i know all of these bans are permanent, unless stated otherwise.
(unofficial) rules:
