Meet No-Bot Registration, easy to use, superior protection without making it hard for your visitors. Easily blacklist (partial) email addresses and domains so they can no longer register an account.
Create one or more questions and a set of possible answers for them and visitors have to answer your question when they register. 
If they answer wrong, they get denied their account.
