Banning a proxy service

I was wondering if it's possible to ban a specific proxy service. Not the IP addresses, but the service itself. We have a problem member who is trying to return and we've found out from a source. which proxy service she's using.

Any help with this would be great.

 

I've been having the same problem.

 

I think Paul M from vBulletin has something for this. What versions are you guys running?

 

I just found this hack of Paul's: Proxy IP to Real IP Conversion - vBulletin.org Forum

Seems like it would do the trick.

 

I have tried that and had no success myelf, unless I aint using it correctly.

 

Ah, that must be the mod mentioned elsewhere today... I'd been searching for "True IP".

 

I've been using that to no success.

 

That mod will not ban a proxy service. Its designed to extract the real ip of someone using a proxy server, but will only do that if the proxy passes on the details (as http headers). By definition, annonymous proxy servers do not do that.
