Somehow my Wordpress site has over 14,000 users. I know from looking at the records that these are "spam users"...
Spam User Email martin28651162 firstname.lastname@example.org martin322929651 email@example.com martin443534673 firstname.lastname@example.org martin640363627 email@example.com
Is there an easy way to remove all of these users without removing my actual "Real Users"?
Real User Email yyyy firstname.lastname@example.org zzzz email@example.com
How can I prevent these users from being created automatically?
