5. Three days later, Joes ip is changed and he can log in as a guest again. He knows that hes banned so he use another nickname instead, that he registered after 'Joe'. He logs in as 'Jim'
6. The tracker checks the database and find that Joe is linked to Jim
7. The tracker checks with the userban-list and find that Joe is banned
8. Jim, Joe and the new ip is now locked out

The blacklisting option means that if any guest is matched with a banned user the ip will be blocked from the forum even before login. If 'Jim' is a shared "troll"-account this also means that all users logged in as Jim, will be locked out of the forum because Joe is linked to the same nick - and banned.

The blacklist in options->userbanning only stops specific ip-addresses, which means that if Joe goes to his parents he's able to see the forum as a guest (until he tries to login as Joe again). If you use the built-in blacklist and using parts of the ip the risk is that you ban a bunch of other users that is using the same subnet.

Wouldn't this block out dial up users and users on providers like aol? (banning one AOL IP affects a whole range of AOL IP's, because of the way AOL's network works)
