It's quite easy to see why you're banned, seeing the posts made in the Tibiantis thread, which have been consistenly off-topic, making arguments for nothing, going on rants over nothing, also your posts are filled with personal attacks to whomever gets in your way.
Trolling users, throwing insults, posting just to stir things up, derailing the thread to intentionally create drama.
Now if I read the rules right, the punishment, for violating the first 4 rules, and nr 6, should be around 7 to 30 days, but you broke more than one rule so who knows. You think the moderator has the rule book next to him and punishes you accordingly to the set punishments? I don't think so..
It's common sense, to see your previous posts, to see if this person actually makes an effort to write anything useful on this forum, I wouldn't be suprised if your ban will be lifted at all.
Asking "why hasn't an admin explained it to me?" while still acting in bad faith isn't going to get you any sympathy, not from the moderators, not from the people on this forum.
