Snapzu has a lot of restrictions in place for new users that keep the power in the hands of veterans that are well liked by the community. I think these systems can prevent a lot of the damage that was done by moderators in the days of olde.
One feature that does this is new users can only downvote 5 times a day, so people can't launch massive downvote raids because they can only downvote so few things per day.

Active moderation and a stable reputation system also aid in this as well as what /u/Victarion said.
