SpamRemover-Removes Spam Automatically

Are you flooded by SPAM? You can save yourself from unwanted junk mail by installing Spam Remover - a powerful tool that filters your incoming mail by content and sender. You know it - SPAM is here to stay. You need an effective solution to your spam problems now before it is too late. Of course, you could take the temporary and increasingly time-wasting solution by deleting them. We're pretty sure you're already doing this once or more often each day, and that you are sick and tired of it. That's why you need Spam Remover, the Permanent Solution for getting rid of unwanted mail, frustration and wasted time
Spam Remover is a plugin for WordPress that automatically removes spam user registrations and other old, never-used user accounts. It also blocks the notification e-mail that WordPress normally sends to the administrator whenever a new user registers (annoying when that registration is spam!) and logs it instead. The plugin adds a configuration panel so that all of these options can be turned on or off, and it logs and fully backs up all user accounts that it deletes, so that you can restore them if you need to.

Key Features:

Automatically deletes user registration spam and other orphaned, never-used accounts.
Very simple, enable and go! Doesn't interfere with the normal user registration process in any way. So, it doesn't add captchas or activation or anything else -- you're free to use it alongside a plugin that does, if you like.
Blocks notification e-mail that WordPress normally sends to the administrator every time a new user registers (instead, logs this event).
Fully configurable, with grace period for new accounts and optional username whitelist.
Fully logs all actions and backs up all user accounts that it deletes so that you can seamlessly restore them if you ever need to.
