When we were growing up, internet was for smart people. Chat rooms and video games were for "nerds", the "cool" people all hung out in person.

When someone wanted to do something counter-culture (i.e the *chan websites), there was actually a shared interest behind it. People would spend time making content and actually doing things on the web.

These days, internet is so ubiqutious that the majority of the users are simply consumers. There is no drive to build anything. Modern day kids aren't going to be spending time trying to figure out how to get around social media bans with technology, because most internet users simply just don't care enough to organize and build something.
