WP Content Filter: Get Rid of Profanity, Abusive Comments
Running a WordPress community comes with many challenges. As your site grows, you will attract trolls and abusive commenters. WP Content Filter is one of many plugins you can use to get rid of swearing and abusive comments on your website. You’ll just have to define the keywords to remove, and the plugin does the rest.
WP Content Filter is pretty easy to use. Just choose which posts and pages to target and add profanities in the backend. You can change filter character and case matching options too. The pro version offers even more features. It actively searches all content and offers you a report of matched terms.
