If every Reddit user was tagged with their age, it would be an eye-opening experience. "Why is this 16-year-old talking about divorce lawyers on r/relationship_advice?"
The opposite has occurred and it wasn't very pretty to look at.
/r/drama banned people who posted in /r/teenagers and brought to surface a whole bundle of pedos
Granted, I don't think anything will change, but complacency is the moment reddit truly dies.
