Anything goes at this point. They have no shame.

For the children might be one way we can get them to support keeping search results private. Imagine some predator who decides to buy the history of certain demographics that will capture those 13 to 17 (and those under 13 who lie). They can then go through the search and look for anything that indicates someone who can easily be preyed upon. Find someone who searches things like how to be beautiful, use the internet history to stalk them on social media, and then use their internet history to form of a connection.

Condense something like this into a 1 minute add, run it as a 'how to' aimed at predators with the intent of striking fear into the hearts of parents who see it, and then end it with a short message on why we should keep internet usage private.
