There was some heavy handed moderation decision that moot made, can't remember what, but he enforced it by saying "
One man's shitpost is another man's board culture". I think about that a lot when it comes to moderation because people tend to assume everyone in the community is just like them; and really only moderators have a gauge on how saturated certain can be.
It's also why I don't like the "free speech at all costs" meme that gets thrown around when $corporation bans $person_i_like. Every community needs moderation and it's often a thankless job that feels like nothing is being done at all when it's being done right.
