WordPress MU

Hey all,

I had my MontySpam expire for a day or two and when I came back to my blog, I found that I had 300+ splogs sign up overnight.

Two questions
1) Is there a quick way to delete blogs/users from the database? Right now I have to click each check box on each page and there are like 60 pages of blogs that are just spam.
2) What is the value of marking a blog as "spam" vs. just deleting it?

would be great if there is a javascript select-all on the tick box, just like the user subscription/role change in users.php

i dont know how to do this tho'

Check out my power tools plugin

Specifically, the cleaning feature.
