I think a lot of people have the same idea here.
Do what you want. You know what your target audience is when writing anyway, so write accordingly. If you feel like a character needs to say a bad word, do it if you want. Or, if you're second guessing it, leave it out. I especially find that in films with external voice actors, it's best to leave the profanity out since a lot of people don't like that to go with their name. Or just give them the whole script ahead of time and let them decide if they want to attach themselves to it or not (which I personally think is best anyway).
To say that LEGO is all for Children is wrong obviously, because we're not kids and we're watching and making brickfilms. LEGO is a medium, you're the artist.
That being said, I don't put profanity in my brickfilms, nor do I really watch brickfilms with profanity. This is purely on personal principle and because I don't like profanity that much. (I mean, I can overlook some, but I just prefer not to).
That being said, cursing for the sake of it just makes the film look dumb. Even in real movies (well, good ones), characters only curse when they mean it instead of just throwing it around willy nilly if it's not natural.
