In my joomla install I have removed the email registration and instead added a Captcha field to the PHP code using the recaptcha.net method.
For some reason I am still getting what I think are spam users (robots) but I don’t know how they would get around the Captcha field.
Anything I should check?
I fixed this using http://extensions.joomla.org/extensions/access-a-security/authentication/7727
