Comedian George Carlin joked about the "Seven Words You Can Never Say on Television," a social commentary back in the 1970s about the pitfalls of censorship.

Filters on devices offer a partial solution. But some parents say they can't shelter their children anymore and must confront the barrage with frank discussions. As one mother put it: "Talk, talk and more talk."
