If you wanna clean up a lot of fake or inactive user's registrations (usually made by spammers) by one operation - this tool will help you to do
Great too for anyone who allows users registrations.
Does what it is supposed to do.
I think I had tried this plugin before and it had failed. However, I just used it now and it queries users and lets you "mass delete". It deleted a couple of users I wasn't expecting, but it may just be because I wasn't paying close enough attention when deleting users. It didn't delete me as the admin and didn't delete the 1 user with other posts... exactly what I wanted 750 other random spam users gone! YAY.
Does exactly what it says it will do. Not bloated by nonsense. Very very easy to work with, got rid of 1000 spammers in a minute
