Do You Have Parental Blocks on Screens?

A group of boys were over at a friend's house. There was no monitoring of using screens and there was no parental blocks on anything. They Googled Harry Potter and Hermione and... Sorry, it's not funny, but I can only imagine. It didn't go over well. If you're gonna expose your kids to the big world where there may not be parental monitoring, the poor things need tools. Like they need to know to put their hands over their eyes before they make a decision about seeing something that's gonna scar them.
