I know this may sound quirky, but you know the original "Post Assignment" gradients and arrows that show a post's AP-balance? Well, I think that it would be worthwhile for extremely-negative posts to have some sort of flashing item or attention getter so that other members of the community can scrutinize them and decide whether they think that the rating is truly deserved. I think this becomes more important with the recent events of AP-balance-dumpage and quick bans.

I took the original images and came up with a little "This post is Ultra-Negative" graphic with which to replace the current extreme-negative indicator.
