Create another 'service agreement' whereby an unsupported hack, or even an abandoned hack, can be picked up by the community of coders to be expanded upon, i.e., the license for the hack becomes a quasi- open-source script. Of course, those picking it up or working on it would need to agree to keeping all credits intact with the noteable exception of 'linkback copyrights'.
A great starting point for something like this would be vBookie. The original author allowed another coder to pick it up but that coder has not updated it since. The new coder is now an offical vB programmer so that's even better - The vB team giving a piece of code to the community to improve upon
