As a moderator stated before, he does not brake any forum rules. Tho his posts are more riddles to figure than point is one thing, but still, no need to say the things you said.
Of course, I usually belives he's on acid or something, but he got personality and I find his topic's fun to read.
To call it trolling I wouldn't say. He's not insulting anyone either, and frankly - if you think he's on acid and just want to say no-go things to him, keep it to yourselfe, rather than spamming insultning replies in his topics.
