I've said it before and I'll say it again - WEBF / Yokel is a classic aspergers person. I think we need to accept that unfortunately he suffers from an illness, and that his affection for the SHAR is nothing to do with genuine concerns, but is a symptom of this illness.
Perhaps the kindest thing to do would be to either continue to humour him, or suggest that maybe the site owners ensure his stay here is ended as a means of helping him recover slowly. He's held this fixation now for nearly 10 years, and I think he genuinely needs medical / psychological help.
I am not trying to be rude / wind up by saying this, I genuinely mean it.
