Delete inactive/spam blogs with one click?

Hi everybody,

search with google but all i found are some old scrips. Won′t use this with the actually version of wpmu.

I search for an: plugin that checks blogs for inactive user (or mass spam) and delete them complete (not the user, only the blog with the content).

Is there any plugin for wpmu 2.8.5 that can works with this version?

merci
kind regards
Markus
