SafeKiddie has Profanity Masking.

This allows you to view an entire web page without being bombarded by vulgar language — a useful parental control.

Over 47% of Facebook walls are covered in profanity and 56% of the comments with profanity are written by “friends.” (Source: The Reppler Effect.)

Many sites, such as YouTube or blogs, permit users to leave feedback or comments directly on each page, some of which are inappropriate or profane. Some Internet filters might block those pages entirely. With SafeKiddie, you can view web sites that include profanity, without being subjected to reading the profanity.
