Not sure. Memory says he ran afoul of Milacron at some point, might have gotten banned.
He'd definitely degenerated into an abusive arsehole by then regardless. Seemed to be posting while drunk. Or maybe he'd been in cognitive decline, in which case I feel for him because that's a fate awaiting more than a few of us if we live long enough.
Anyway IMO a cleanout here on PM was way overdue. Things have quietened down some now the rabid RWNJ's and humourless LWNJ's have either been booted or placed on sufficient warnings that they've pulled their heads in and stopped inflammatory posts. Let's hope it lasts.
