The Yahoo! Message Boards Profanity Filter allows registered users to block commonly-used profanity from their viewing environment. In order to use the Profanity Filter, you'll first need to sign in with a registered Yahoo! ID. If you don't have a Yahoo! ID, you can register now. Registration is free and easy.

The Profanity Filter allows you to control how you want to view messages with profanity in two ways. You can choose to view the messages with the profanity masked with italicised symbols (@$&%), or you can have the messages containing profanity hidden entirely.

You can also choose between a weak setting for exact word matches or a strong setting that filter spelling variations.

Please note: Some messages still display profanity due to the timing of the posting and the release of the Profanity Filter.
