I don't know for sure, but I suspect that founder changed his profile name to what it is right now and then put Icey in the corner (meaning, blocked access). Whether that's temporary or permanent...no idea.
Beyond that, my perspective is that Icey was/is here solely for attention and turmoil. He was able to generate plenty of that when he had SJG as his proverbial "straight man", because SJG would endlessly reply to anything directed at him or anything that touched upon one of his many triggering topics (which made the word "autism" radioactive on this site...). So, between Icey and his useful idiot, it was easy for Icey to drown any thread and pick fights.
When SJG evaporated, Icey had a harder time getting all the attention he required (minus using SJG as a forum gasoline). He then tried to get his fix the same way via the many sock puppets of cacaplop, but that didn't work out. So, then he started posting stuff about the the family members of people here, and then there was the Great Vegas Meetup Drama, and then he went "full retard" and spoofed 25.
My 2 cents. He's a moron. He'll probably resurface eventually.
