I dont know if I am asking something on the wrong place or not, but I use(d) this excellent plugin to clear up data in my database, and it has been absolutely great!
Im not sure, is this an official supported plugin from you, or is it not? I do recognize James though :wink: https://premium.wpmudev.org/blog/wpmu-power-tools-plugi/
Anyway, if this is the place, and if James is listening, the plugin would be greatly improved, well usable now days since there are in my install anyway quite a lot of false positives of spam blogs that makes it impossible just to clean out every single blog and user flaged as spam.
A much more usable setting, and I think, at least in my ears, simple extra setting would be, delete all blogs/users/comments/etc before "date X". That way, I could type a date some months ago and still be able to keep my database free from garbage.
