Hi,
We have made it so that all spambots who sign up to the bbp forum automatically get the role “no user role for this forum” (translated from German).
The thing is, when i go to my wordpress “user” settings, they are all under the “subscriber” role. As are all the real forum users.
I would like to have an option at the top to select just the “no role” users, so that i can bulk delete them all.
How do i do this?
thx.
btw, i dont want to install a wp-admin hide plugin as these have conflicted with our theme, and therefore i have to deactivate them.
