Anti-splog and existing blogs. Is possible to check them?

Hi, I've just installed the anti splog plugin, and it seems working. (I've set as spam some existing blogs and removed them... and the plugin set by itself some new sblogs).

Is there a way to check all the existing blogs with the plugin? I'm not very happy to check manually thousands of blogs and set them as spam or not. Something automatic would be very appreciated.

Does the plugin check also for the spam comments? Otherwise, what do you suggest to use for them? (and a way to remove old spam comments)

Thanks
