I don't know how popular this suggestion is going to be, but I feel that there should be an area in the JY where new members have to post for the 24 hours of being a member and the post count wouldn't count there, and they can't post outside of it until that 24 hour window has passed. This would help to weed out the people that are only joining for hacks and are spamming the 10 required posts.

I recall the post spamming for hacks being a huge thing back in the day and that was solved by the UG, but since no one has applied for UG in almost a year, I feel that creating a sandbox style area where newbies have to post so we can weed out the bad seeds would be beneficial to the site over-all. It would also give us an idea of who has actually returned and has intentions of returning.
