No, if you are perma-banned, you are permanently banned from the forum. As I said, in our forum serial reporters, problem children, people that were serial liars, thread blower-uppers, people that just caused a lot of work for us mods were permanently banished from our forum. You'd get a 5-day suspension, a 10-day etc. after a 20 day, you'd get permanently banished from the forum.
Again, I don't know what they do here.
