Prevent unwanted users from registering on your WordPress site by creating custom blacklist and whitelist rules.

Note: You must have a call to wp_head() in your template in order for the JS plugin files to work properly. If your theme does not support this you will need to link to these files manually in your theme (not recommended).
PHP Version: Plugin uses a structure which was introduced only with PHP 5.3.0. So if the version of PHP is lower Plugin does not work

Used to block spam registrations from known domains - if you read the instructions carefully it works beautifully.

I sent an email asking to modify the plugin to be compatible with my registration form and the team, really very responsive, did it in a few days. Then I uploaded a file with more than 22000 disposable email domains to block them in my users registration page. The plugins works perfectly without slowing down the registration process.

The most people are using free emails like aol gmail freenet gmx and so, why to forbid them. And spammer users are using or so. There is no blacklist for them. I really don't understand the sinn of this plugin

This plugin works as expected; killed all spammers and false/disposable emails addresses which is what I needed for years! No more spammers – wonderful!

We are sorry, but you need to have at least PHP 5.3 to run this plugin (currently installed version: 5.2.17) - please upgrade or contact your system administrator.
