I have banned them. What I need to learn to do next is:
(1) Hard-delete all of the content these "users" have posted.
(2) Limit the number of posts per day a new user can post until I can review them (specifically, add them to the new "Reviewed" secondary user group).
(3) Find a way to keep these ******** out of my forum.
I'm using XF 1.5 with the Change Date add-on installed. I do not require an e-mail to be replied to in order to complete registration; I do this to protect users' anonymity.
Any help would be appreciated.
