Problem with that is that you can only delete groups 20 at a time. The spam got bad, I have over 4000 spam groups and I need them all to go at once, I don’t exactly have time to repeat the same process over 200 times. I was asking about a measure to get rid of all of them at once.
That’s massively outdated and doesn’t work, and I put the anti-spam into place after I noticed this and it works great. But that organizer is for very, very old versions of buddypress.
