This plugin provides a possibility to block comments based on words of a predefined list. The built-in lists of wordpress only allow to send comments to the moderation- or to the spam-queue but not to block them completely. This is remedied with this plugin, which allows to block comments based on a definable list.
Attention #1: Use wordlist with care, there is no logging of the blocked comments!
Attention #2: It will also match inside words, so “press” will match “WordPress” as well!
