WordPress Plugin:  JP User Registration Blacklist

Check out my first WordPress plugin, which you can view here:

JP User Registration Blacklist

The main purpose is to prevent spammers from registering as a user of the site.

Features:

• (Version 1.7) E-mail confirmation token
• Asks a simple math problem during registration
• If the user’s e-mail or IP address is listed in the Comments Blacklist (Discussion Settings), it prevents them from registering.
• Lists the user’s IP address in the “website” field, allowing the user to see the IP from which the user registered.

Let me know what you think!
