Just re-subscribed

grandfather all the existing 0-post accounts and implement something that prevents bogus accounts going forward.

I think telling any new folk who sign up that they must post within 30 days or have their account removed, even provide a link to a "welcome" thread where they can post a hello, is acceptable. Any older accounts that are lurking spammers will show their hand eventually and get purged then. Might take longer, but it will get to the desired result.
