I need to clean a WordPress Web site of SPAM users. I checked the Users list and noticed that valid users have a proper Name listed; SPAM users do not have that value and a - is displayed instead. How do I delete all users with a - posted under the Name field in Wordpress Admin? Preferable, i would rather use thr MySQL Database to do this, but if it is too risky, deleting from Admin is okay, but very slow navigating through each screen, etc.
Tks for your feedback.
