He isn't banned, he's hellbanned, and he knows he's hellbanned. I leave on showdead too, and I'm glad it's an option. I don't want to remove the option of people to avoid markov chains of racial slurs and religious manias when they're reading their tech discussions, though.

If you really want more Davis, email him. I'm sure you'll get an interesting response. If you can't ban him, though, you can't have any grounds for banning anything.

edit: Everybody knows who he is, everybody knows he is pretty awesome, and everybody knows how to read his writing if they want to. Isn't that good enough?
