Define a set of things that many will want to censor on. Put it in censor.txt. A browser in censored mode pulls the file for the domain, checks if it contains any tags that it's set to block. It's treated like anything else a web browser might load, cached if possible. In uncensored mode it doesn't matter if it exists, it's not downloaded. Make a standard set of tags and a yes/maybe/no response to them. (Maybe is for a website that has user content that permits such stuff.) I do agree it would be defeated in many cases, though. Tech-ignorant parents aren't going to be very good at stopping tech-savvy kids.
