antispam for 4chan

Is it possible to make an automatic anti-spam based on the report feature?

Maybe add an extra option.
O Rule breaking posts
O Illegal content
O Spam

It will check for similar posts in all boards, if more than one post with a similar composition were reported as spam by a X number of users it will be flagged as spam deleting all similar posts and blocking it to be posted again. Something similar to the gmail anti-spam.

I agree with >>29 that with proper heuristics, spam could probably be filtered out with a pretty good ratio after a while. Of course, banning a few more subnets couldn't hurt as well (preferrably those posting AnonTalk and virus links, I always rage when I see that).
