I'm not even sure where to begin to get this into the right hands but hopefully one of the moderators hill has some connections ;)
Basically the WP plugins repo is in some serious need of a clean-up. And the easiest way I can think of is a "renew it or lose it" policy. I'm confident we could clear out thousands of "crap" or "expired" plugins if there was a renewal process in place.
Thanks for listening and passing this along!
