What is WP Polite-ifier?
WP Politifier enforces a certain level of politeness in your comments, replacing recognized swear words with acronym’ed asterisks.
Since I also believe in freedom of speech, the original text is preserved in the title attribute, visible on mouseover. However, it solves the immediate problem of keeping my comments and blog “family safe,” at least at first glance. It also has SEO benefits for publishers running Adsense who want to maintain high-quality text without swearing or cursing in it.
The badwords list is editable through the administrative interface, and kept in a text file in the same directory.
Please download politeifier.zip from the official Wordpress Extend site, which will always host the latest and greatest version of this plugin. To install, drop badwords.txt and the wp-politeifier.php into your Wordpress plugins directory and activate in the administrative interface.
Mike Smullin suggested a patch which fixes a bug where the badwords.txt file is unable to be located. This has been fixed.
