You can always just delete your account. Granted, that's easier for me to say as an adult than it would be for your average peer-pressured teenager. But that's where parents can help.

I think eventually, teens will see social media as "uncool" in the same way as they see smoking cigarettes as "uncool" (in some countries). It takes a lot of social propagandizing to popularize that idea, but we did it with cigarettes and we can do it with social media.

We need to make being off the grid cooler than being on it. Privacy is cool!
