I currently have problems with "spam registrations". There are around 20-30 every day. Recaptcha is already active. What else could I do?
Please note the user registration and account creation doesn't have any relation to wpForo. It's being handled by the WordPress side. We've created FAQ topic, please check it: https://wpforo.com/community/faq/how-to-stop-spam/
Here is explained the way you can solve the issue.
