In the case of Reddit, niche subreddits can be handled by a couple of moderators, but once they become popular and you have thousands of people breaking the rules, you need a full time team of capable moderators. In forums like the old Slashdot or here, users can moderate with varying degrees of skill with their votes, but users of popular subreddits will happily upvote a serial reposter in the thousands before the mods can take action, they have no idea what the rules are, and even will get mad if the mods "oppress" them. On a side note, I believe Internet usage should be an obligatory subject in school, but not for etiquette, but for common sense and resiliency against manipulation. Add socialization, mental health, and parenting too if you're changing the study plans.
