The problem isn't the scale of Youtube, it's the scale of the Internet. If Youtube didn't exist, we'd still have billions of people posting billions of videos, and who is going to take the time to police it all? Extending your argument about Youtube to the Internet & humanity, I think you're arguing that if we cannot address these kinds of problems in our Internet, then we shouldn't fucking build it. I disagree. I think we're better off with the Internet even though these moderation problems are unresolved.
