Anti Splog Plugin Not Functioning

I’m having an issue with this plugin. The plugin detects a ton of spam blogs but when I try to mark them as spam it will vanish like it marked it as spam but on a page refresh the blogs re-appear and do not end up under recent splogs. It seems like it only does this for splogs with a score of 60% or higher. Even if I try to spam them by IP it does the same thing. It will say I am about to mark 5 as spam – I will OK it. It will appear as though the changes were accepted but on a page refresh they just re-appear.

Any ideas?
