BuddyPress.org

We currently have a site running WordPress and BuddyPress. We have ~200k users at the current moment, some of which we know are spam. We’re redesigning the site and need to clean our user list before that happens. I’ve put some things in place which has almost completely stopped spam signups, but there are still years of spam signups which we need to nuke.

Anyone have any advice on the best way to do this?

Thanks!
