Also not really a fan of when someone says some dumb shit and a score of hexbears descend like vultures to all get their super cool dunk in. Most of these replies contribute fuck all, often enough it's just bears replying to each other long after anyone else, and it bloats threads, making them less readable and keeping them hanging in the sort.
Act like you've been there before. It's like in a twitch chat when there's something obvious to say and a hundred people fall over themselves to be the special little poster whose comment gets attention.
Once a couple people have replied to an offending comment, just move on. Really think about whether whatever you want to say hasn't been communicated already.
