The episode was way too kind to the role of moderators and their 'sacrifices'. They did not cover the other side of moderators. They simply need to go to a forum like Reddit and you will easily find moderators that let the power go to their head, will outright BAN you from a forum if your views do not match theirs. I was once banned simply for asking a legitimate question (it was not a 'trolling' type question in any sense).
