This is the reply I've recieved from vBulletin...
I never said that they we're using it for "illegal purposes"Unfortunately legally we cannot control the content of a site, no matter how offensive it it. As long as they do not violate the license agreement, there is nothing we can do. You can view the license agreement here:
http://www.vbulletin.com/order/license_agreement.php
[Note: The infraction must be on the vBulletin forums for us to take action. We have no say in anything other than the vBulletin pages. Also in regards to using the software for 'illegal purposes' we are not qualified to determine legality in any jurisdictions. If they are convicted of something regarding content on their forums then we can revoke a license.]
If you suspect a license violation, please report it here:

Otherwise, if you wish to make a complaint, you will need to contact the webmasters of that site and/or their web hosting company.
