It was the disdain of the more power-hungry admins for ordinary contributors and the unwillingness of Arbcom (made up, of course, largely of power-hungry admins) to reign them in that made me stop writing stuff for WP. I haven't posted anything under my user name for well over a year now. I have, however, made a few posts to discussions where admin abuse was visible. A certain HJ Mitchell (now where have I seen that user name recently?) blocked me for posting whilst logged out. This, of course, is not a legitimate reason. And someone from the block-first-think-second-but-only-if-you-can-be-bothered school blocked me for being User:Vigilant despite my editing from a static IP in a different country from where Vigilant lives. 
This site lets people like Mitchell climb the  greasy pole through picking on others. (Just look at his activity log and how few of the people he has blocked have blue user talk page links and they aren't all vandals. WP:BITE or what?) Hopefully his plans to get on Arbcom have been pushed back somewhat by this latest escapade.
