I would like to have your opinion on this.
I think it's a possibility we have to examine.
He probably does what he does in this forum ON PURPOSE!
Mainly to draw attention on him, to irritate everyone, or certain people he may target, to be intentionally rude, to show up like some kind of a lunatic, to make an impression, to draw up suspicion on another member, and 10s of more other reasons. All ON PURPOSE.
Just look how many pages get filled up just for what he says, and what he does.
As for discussing anything, I don't remember seeing him engaging in any serious discussion.
He's just throwing mud here and there.
If it's on purpose then he might be a perfectly normal individual who is just using the forum to play games and have fun.
