Spammer's choice

I’d quite like to be able to harness the efforts of the comment spammers and MT-Blacklist so that when a spammer fails to comment on a posting this fact is noted and posting can get mentioned on the front page as the current “spammer’s choice”… Sounds mad, but since I have a lot of content now, it would be a way of bringing some old stuff back to the front page - in the same way that the comment section does…
