Comment 2 for bug 106501

Okay. To make progress here I'd like to see a study into what constitutes an "unused project". Does it only cover projects which were registered and then never touched again (so they'd have a product and a productseries and nothing else) or does it cover projects which were registered, had specs and bugs created, and then nothing else happened to them? The former picks up a large number of cases (maybe 60% of bogus projects) but it's often the case that somebody will create associated objects to test the project with -- and there you have something which isn't auto-deleted. Should we take care of this manually as we are doing today?

And, to be clear, are we saying DELETE projects, or just mark them as inactive?
