Custom Registration Link allows you to modify the registration link of your WordPress website. This will result in greatly reduced spam registrations. The default registration link is “wp-login.php?action=register” and is heavily targeted by spam-bots.
Reduce spam-bot registration
User agents who will try to access the normal registration link will be redirected to a page telling them that registration is disabled (wp-login.php?registration=disabled), in order to reduce spam registrations and with the potential benefit that learning spam-bots will not try next time as they “think” your website doesn’t accept registrations. Normal visitors will go to the new registration link. The day I installed Custom Registration Link, all of my spam-bot registrations suddenly stopped.
The new link is customizable in your WordPress dashboard, and you are strongly advised to change the default value for something of your choice so that your website is unique.
The installation of the plugin is very easy. Just extract the archive into your wp-content/plugins directory, and you’re good to go.
