Tired of "garbage" users in your Joomla site? User Killer is for you.
User Killer is an essential plugin for Joomla systems administrators. Most Joomla sites are plagued with "phantom registrations".

Have a busy site? User Killer won't bog your system down. The plugin only does significant work once every 24 hours (this interval is also configurable). If your system has a large number of users to clean out, User killer will remove them in small groups, so your server isn't overloaded by a massive clean up.
User Killer removes users cleanly by using the Joomla core functions. This causes user delete events to fire, which will clean up users in (well-written) extensions that require extended user information (access control, forums, social networking, etc.).
User Killer requires PHP 5.2 or higher. Download here.
