If it’s anything like Reddit, it would devolve into being mostly creepy adults.

Most of us would post on forums as teens back in the day, so it’s hypocritical to try to keep them from doing it too. The only places we should run them off would be communities we specifically make for adults. They don’t necessarily have to be NSFW. Sometimes it’s just nice to have a community where everyone is old enough that they get the same references and are in similar stages in life.

General music and hobby related communities really shouldn’t be blocked off, though.
