Is there a way to properly stop spammy new members?
I've already set my registration process to approval, and asked people to make a specific comment about the subject of my forum, and why they would like to join, but I'm getting an increasing amount of new "spam" members - that is Russian, or with very dodgy email addresses.
Even without the approval mechanism in place, I'd get about10 new spam sign-ups a day, and even with, it actually doesn't cut down my work of deleting them, it just ensures they don't get to post any spam first.
Ideally there's be some kind of captcha plugin, a question and answer, or picture-match mechanism for the registration page, but I've not seen this amongst the add-ons.
I'm happy to build something myself if someone (devs?) could point me in the right direction to which files to tinker with.
