Banning users with a non-Static IP

[wideopen]

Have several Users that I have banned that use a Non-Static IP address . So they come back when ever they want. Does anyone have any idea how to stop them? Is there a way I've missed?

Thanks in advance.

ban usernames, not only ips

I do they just re-register under a new username and start crap again.

there is nothing you can do about that actually...

humans will always find a way to deal with security. what you can do is talking to them seriously, to see why they do trolls... if there is more trolls than real users, the only solution is to close your forum.

Keep a long and report it to the abuse dept of there ISP, unless they are going through proxies, in which case not much you can do.

Some Proxys don't support trolling of forums etc, so if did report it to the proxy provider they would possibly send you logs of there IP or just ban them, but there are thousands of proxys...

I know every trick in the book when it comes to this only because I've been running forums for, well lets just say, a very long time.

If you ban non static IPs well there goes most of your users because most ISPs give dynamic IP addresses unless you pay a $5-$10 fee to get a static IP (mostly businesses have this its not really a residential thing).

What you could do to start off is get a list of all those E-Mail services, like dodgeit.com or pookmail.com, that let you receive emails without having to sign up or login. This will stop most people from signing up if they use any of the hundreds of major email services like this.

Also there are a few proxy blockers for vBulletin, some where on the site, or even better some hosting companies have options to block proxys from viewing your site. SO just look around in your host control panel before you do anything to your forums for this.

Here's how I combat this problem on my forum:
* Use Multiple Account Registration Prevention, so when they sign up for alts, the alts are put in a usergroup without posting rights.
* Use Proxy to Real IP Conversion
* Setup a promotion system such that when someone gets -5 reputation (or -10, or whatever) they're moved into a usergroup which makes all their posts moderated. Then encourage members to moderate them.
* Use the 'miserable users' plugin to make them think your server is sucking, but they are not banned, so they never bother trying to evade the ban. If you're really evil, combine this with Multi-Account Registration Prevention. Set it to use cookies only, and put new accounts they register into a group with limited posting rights and to which the miserable users plugin also applies.
* Limit the abilities that new accounts have, so you can catch alts before they cause major damage.

I haven't used it myself, but you might also want to try :
* banning by cookies
* Use the community-driven moderation system (I forget the url, it is on vb.org somewhere)
* If your users don't know about cookies, disable the "log-out" button so once their account is banned, they can't logout. WARNING: they may clear all cookies to get around this, and this will prevent above steps from working.

Also, if you gave us more detail about exactly what they are doing to be a pain in the ass, that would help.
