I'm not sure what you see on your screen but on mine every thread he posts in this forum has a 4 or 5 rating. And they always seem to appear right after he posts something.
As far as the ratings go, I really don't see the sense in them being here at all. Seems kinda silly to me but whatever cranks peoples tractor I guess. It takes all kinds you know. Probably one of the many trolls that patrol this place trying to undermine every conversation, make continuous sarcastic remarks and make snide remarks to people they don't like. I dunno. I wouldn't worry too much about it though. It's just something I've come to accept and expect here.
Just my 2 cents.
