This is a GREAT plugin. Very nice job.
I know that this is a stretch but thought I would ask...
A new feature to die for would be to somehow flag/identify/segregate the posts and comments that have the offending content.
That way the admin could deal with the offender, and modify the post or comment content as they see fit.
As it stands now, the only way to find the bad content is to visually see it on the site.
