If you open an online community and neglect to moderate, you're just giving the most extreme people of any side a free megaphone. It's irresponsible. If you're not going to moderate, turn comments off.
For social networks - How do you do it at scale? You don't. Give groups the tools to govern themselves. Let users control what they see. Eliminate the timeline, and free for all commenting on posts. I don't care if it hurts your engagement metrics. Don't like it? Then I support legislation to regulate you.
As opposed to simply not using those services? What gives you the right to determine what comments people are allowed to have on their posts?
Thanks for giving me a needed kick in the head!
In that pursuit, internet culture subconsciously turned itself into a calloused nub, a place where so many “jokes” are the equivalent of running and shouting “fire!” in a movie theater, and a place where the biggest joke of all is the idea of caring about anything in the first place
