Copy/pasting into Google isn't really what I'd call an effort. And I was doing to because I don't like getting rage baited. Confirming sources is a good habbit.
The usernames are not pertinent to the sentiment. However, they could cause a hassle. So blanking makes sense.
If there were dangerous or responses that merit a response, ok, but for trying to make a point of "comments are full of vacuous crap", it doesn't matter even in theory.
Maybe if the post were making a point that people didn't agree with, it warrants some clues like a citation to back up the claims, but this is just a circle jerk sort of post, so no one's about to say "no, Reddit only has deep and meaningful commentary, you need to prove that comments like this exist".
