It's mostly common sense, although since our definition of irrelevant is different to the actual definition of irrelevant we just need to define it for those who still don't understand.
Fair point, obviously newer players to the forums will not understand to policy on irrelevant posts as they aren't experienced on the matter, and while most of the posts on the unban request were relevant to the topic, they were irrelevant posts according to our policy. It's not too clearly defined for the Tribunal Section on the help document like it is for suggestions, just needs to be cleared up a little bit thats all.
