This hack is good for mods to do on spammers and then report it to admins for banning.
This hack also allows you to just stop annoying people from being in a forum. (people that are dumb and post stuff not even related to what the forums about)
Yes they can log out and veiw the posts but they still won't be able to post if you don't allow guests to post. It also works great if you allow users to only register with one name per email addy or use registration aproval.
