Thanks for clarifying the ban to me. Now that I understand why it happened I still don't see why it deserved a perma ban without warning. I mean I didn't do it to antagonise anyone I just thought it would be a laugh, even the 5-10 other players were joking about it as well. I must confess that I must have skimmed over the "must attack" part in the rules but I don't get why I couldn't be warned otherwise or temp banned.
P.s I might have looked at an outdated set of rules as I couldn't see anything about not attacking, build, afk etc.
