There was a member named "siiisooo" who vanished completely. He would reedit his posts so the replies made the replier look like a fool.
That's when I started to use quotes for sketchy posters.
PS I had no idea mstechca didn't like walters, I thought they were related somehow.
I guess a moderator could see if the postings came from the same IP address. But it is pretty easy, for most people, to change their IP and I didn't see any thick posts asking how to do that using a banana.
