I found a way to filter hurc ast. When I rescored the window, I noticed several other regular posters (won't mention any names because they may be innocent) were also filtered. Oh, hell, filtering on message ID is going to take out innocent people. No good.
BUT.... when I opened all the filtered posts by several different posters, I noticed they ALL had more in common than just a posting org.

I find it hard to believe this is a coincidence. I offer that hurc ast is a sock puppet as well as a few regular posters who always play nice and seem to be model citizens. A few of them are hurc ast's favorite targets (sock puppet puppet show?)
