Handy hints and ... kinks
A web porn filter can serve the opposite purpose. There are two names and faces that I don't want to see when I'm wandering around the web, because they are guaranteed buzzkills. One mention or glimpse of either one, and any hope of fun later in the day disappears. Fortunately these faces aren't in the news constantly, and fortunately they're fairly unusual names. Otherwise there wouldn't be any point in filtering.
I set up the 'Procon Latte' filter on Firefox, deleted all the default porn-related keywords, and put those two names in the list. Sure enough, any page that includes either of those names gets blanked out!
