Hi, one of my sites is getting absolutely crushed by an overwhelming number of spam registrations.

I have to approve the users first (New User Approve plugin), so I can deny them on the admin end, which prevents them from wrecking havoc on the site as a spammer. However, I need to stop them at the registration (front end), also. I use BP Security Check (plugin), forcing a math equation for registration, which seemed to work until recently. Is there something else I can do?

Please help-I have so many BP registrations still coming through… Thank you!
