Hacker news has a minimum karma requirement for downvoting; you can't just create an account (or a dozen accounts) and start downvoting something you don't like, or to harass someone with serial downvotes. You must first attract a certain number of upvotes for your comments and submissions.
That fixes many of the abuse problems with downvotes.
HN situations are also monitored by the site operators themselves, who intervene. YT is too vastly big for that.
