In all seriousness, the "language you don't want your kids to see" is probably leaving open this kind of problem. That isn't as clear as I think it's intended to be. Some might see it as very restrictive and others might not take it seriously at all. I think the message is sent by the rest of that paragraph, you could probably just do without that line and save the confusion.
It's a fair point. We'll give that some thought.
