He's banned quite a few of us, mostly without any reason other than, say, posting a link to Intensity. There was a scandal about him reading member's PMs, and another about monetary donations to the site, and many of us didn't just watch it all unfold in silence. And if you go back in time, there's been many, many examples on how Alex has worked against his moderators, micromanaging them at every opportunity.
I got banned when I wrote that WP's like a really bad daytime soap. I am still banned, as far as I know.
