I’ve started deleting users who haven’t commented on, or posted, anything, to get rid of the many likely-spam/bot users.
The bulk-delete tool I’m using doesn’t let me filter on whether a user has a profile image, and it appears to have already deleted at least two legit-looking subscribers. So I’m holding off deleting more for now.
Please login and comment/post on occasion, at least for awhile, as I clear out inactive users. (I’ve added a plugin to reduce new-user registrations from known spammers as well.)
Thanks for your cooperation!
