Roblox has a bad word detector, and it blocks words that are not even bad words (Come on now - I'm not even allowed to say my real-life name on Roblox without being banned for swearing!). I don't want that to happen to Scratch.

Unsupport.

The Bad Word detector won't allow you to type this:
and so it will freak out on things people who use pen constantly use, like this:

set pen color to (join[0x][00ff00])

However support for the Bad Word Detector hiding inside the ask block too, though I'm not sure what will happen if the user types in something it doesn't like.

No support. Plus this is a duplicate of something I can't find now. Like @DaSpudLord said, people always cheat with the words by using dashes, accented characters, or misspelling.

But what if I was talking about the sea bass I caught last weekend? Or the new Assassin's Creed game?

Negative support since this will break far too many projects.
