banning user help
 

ok im having a problem with a user this person is keep on making users from the same ip adress and i banned that ip and he keeps on making more and more usernames lol how do i stop this from happening and i think i banned him right i went to the banning option and put in that ip adress.....is that how u ban users lol

actually there is no absolute way to ban a user completely if he wants to annoy you further and knows the ways.

there is a troll ban hack by Erwin, which can help you.
Another way is to enable moderation for new users, that way he cannot do much more, until you allow him to do, but it also means more work as you have to check through every new user ;)

Try the miserable users hack or the tachy goes to coventry option in your admin cp.
