Throwing around with definitions doesn't work. Everyone know what that abbreviation usually stands for.

Filtered words are blocked in urls too. The filter's purpose is to block swearing. If everyone could swear just by posting urls containing swear words, that would kind of be defeating the purpose of having a filter.

The acronym filtered generally does not mean "What the Freak" or any of the others the page mentions. It generally means "What the (expletive)" and that is how most people interpret it, and how we do that. The other interpretations are ones barely ever used. "Way to fail" or "Where's the Fridge?" isn't exactly what people usually mean when they use it.

There would be no reason to have a censor if people used acronyms to say exactly the same. Which is why they're blocked.
