Is there really anyway to enforce that? What's to stop them from just creating a new ID? It's kind of like when Major League Baseball bans someone from ever coming back. It's pretty easy to get tickets and with 40,000 people pouring through the turnstiles each night is anyone ever really gonna catch them. I guess we're just relying on them to get the hint and taking away the season tickets in their name (Forum ID).
Oh and add my name to the list of people who wish Tibbs would confine his antics to the Lavender Room.
The originating site (IP address) of the posting is known when the post is made. Dan can (and does, I believe) check that IP address against a banned list. It does not work in all cases (like if your IP address changes dynamically), or if you post from public computers. Even then, he can determine a range of IP addresses that you've used, and block 'em all.
