Can I block a certian IP from registering?
 

This one idiot keeps getting banned, clearing his cookies and then re-registering. Is there any way I can ban his IP from registering?

Ban the IP

Is there a way to ban the IP from Vbulletin or do you mean a htaccess server ban?

an .htaccess ban is the most effective, banning ip's through doesn't work very well.

I have 16K members, I keep finding him because of his IP, he has a distinctive IP address so banning his IP would get rid of him....at least for a while.

you can ban ip under the vb options. it is under user banning options. The only problem is that he may have his IP address changed. I know comcast in my area has changed my ip once.

Banning the ip works well for the less bright of people - I changed the message on our forum so it doesn't actually say your ip is banned - I've always thought it a bit silly to give these idiots a BIG clue as to how you banned them.

Perhaps you can install the miserable users hack but change it so it works off that specific ip rather than a usergroup. That will confuse the hell out of him and limit him.

Any way to just block an IP from registering more than one account?

Bringing up an old topic, but a hack that would like like the IP ban in the CP but instead blocks the ip from registering again (maybe by just giving a plain old 404 error page upon that ip trying to register again) would be cool...

Why not just ban the IP you ask?

Well, I would like the banned user to still see the board and see the psots in reply to whatever it was that made him get banned...
