Bad Behaviour spambot mod? Or a honeypot system?

[Ronin Six]

I'd also love to see this ported to VBulletin. Just have to clarify for those that it's possible to do this without violating your VB license. From Michael at Bad Behavior:

Bad Behavior cannot currently be used with vBulletin due to licensing issues. The vBulletin license is incompatible with open source extensions, thus open source software such as Bad Behavior cannot legally be used to extend vBulletin without a license exemption granted by the copyright holder of the open source software.

Such a license exemption stipulates that the proprietary software is not subject to the open source license governing the extension, and is required to protect the intellectual property rights in the proprietary software. Without such an exemption, it would be impossible to fulfill the requirements of both licenses. Attempting to use Bad Behavior as-is would cause you to violate your vBulletin license.

I am willing to grant a license exemption for code which connects Bad Behavior to vBulletin; I have done so in the past for other proprietary software such as ExpressionEngine. However, since I do not have access to vBulletin code and developer documentation, I am unable to develop the connector myself. If someone were to develop such a connector, then I could grant an exemption to that code, allowing it to legally be used with vBulletin.
