I've installed Spam Karma 2 on a blog that has over 2,000 comment spams and (maybe) fifty legitimate comments. These comments were imported from b2Evolution and Spam Karma put them all in the "approved comments" category.
First of all, is there a way to make Spam Karma re-filter all comments on a blog?
Second, I accidentally sent some legitimate comments "to moderation" but I can't figure out how to recover them. "Recent Spam Harvest" only shows maybe thirty recently captured spams.
