Darth Id was rude for a very long time to many posters, including me. I remember getting worked up at one point, but learned to just mostly ignore his sophomoric humor. However, he fixated on Warbler and knew he could get a rise out of him. He was always just obnoxious enough to hurt Warbler, but he was cautious not to go so far as to get in trouble. He was pretty clever, but he needed to go. I believe the new rule changes were part of that.
The new rules and his final spiel about overweight women eating ketchup.
Not to anyone directly. He was just horribly obnoxious and ignored requests to tone it down, which could be construed as rude.
Not to mention insensitive.
