I was once on a list (well, newsgroup) that used a bot moderator.  If 
the bot recognized your e-mail address, your post was immediately 
approved.  If your e-mail address was new, it would send a confirmation 
e-mail (with a unique random code) that you had to reply to.  The vast 
majority of spam is (a) automated with no human attention and (b) has an 
invalid return address, so the technique was very effective.
