User restrictions- field comparision In my site, I have various fields for user registration along with image captcha. Though I get fake registrations at least 3 per day. I found that "username" and "address" fields are identical by value in all those registrations. Is there any way to deny access to those registrations?.
Use Botcha. This will effectively prevent bot submissions. Don't use short term adjustments for Drupal defaults unless you've used your site for long time.
