User 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
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.

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

Tried activating. Says 'Failed due to Fatal error'
Does not work with many WordPress sites throwing a fatal error about mysqli.
- Update to code that suppresses new user registration notification email.
WordPress core made a change to the API starting with version 4.3.0 of
WordPress, so this update to User Spam Remover fixes the problem where
the user gets a bogus registration notification email and is unable to
complete site registration. Props to Oliver @ www.webmandesign.eu for the
Now requires mysqli. If your PHP version is < 5.5 you may need to force
WordPress to use
mysqliinstead of the older
mysqlextension. Just add
this line to
wp-config.php, near the top by the other DB settings:
- Now detects and adds absent MySQL indexes to wp_comments.user_id and
wp_links.link_owner columns. Greatly speeds performance and enables use on
much larger databases. Big props to Raph Koster for help debugging!
- Enables MySQL sql_big_selects config var at runtime for use on shared
hosts and other installations where this is disabled by default.
- MySQL SELECT errors now logged/shown to the user as appropriate.
- Hard limit of 1000 users per deletion to prevent long-running operations.
Upped limit to 10000 records per SELECT, thanks to improved SQL and indexes.
- No longer deletes users with only comments marked as “spam.” This is a
small functional regression, but it speeds SQL performance. Once the spam
is permanently removed these users will be deleted anyway.
- Minor bug fix affecting settings page user list display w/ bbPress users.
- Changes to method visibility. Many previously public methods now protected.
- Code refactoring.
- Version/compatibility bump so that wordpress.org plugin repository info is
- Added check for wp_usermeta ‘last_posted’ record so that users of
database-integrated bbPress installations are not deleted if they have ever
- Added hard limit of 5000 records to prevent long-running operations.
- Added a list of user accounts pending deletion to the settings page.
- Style fix to inline error messages per r16205 changes to WordPress core
- Miscellaneous minor style fixes.
- Added standard WordPress Users section icon and printing of status message
on options update.
- Updated deprecated PHP syntax for string access by character in lcfirst().
- Very minor refactoring and tweak of message text.
- Fixed weird edge case where no usermeta records exist for a given user.
Before: this caused user removal to abort and an error message to be logged.
Now: any such users are deleted.
- Added nonce checking to “Remove now” button on admin page.
- Slight code refactor to remove buried strings.
- Cosmetic change to log strings so plural “s” not added to singular words.
- Initial public release.
- Tested using WordPress 3.0.1 and PHP 5.2.6 and 5.2.14.
