I support AFK logout because:

1- I'd like to have new people be able to make characters on my server.
2- If you're AFK you should get logged out. There's no bazaars anymore, there's no need to be AFK.
3- If you're AFK in a DF queue, you should either do something in the game while you wait or log the hell out and free up the DF for people who are actually playing.

If you have better things to do then go do them.
