Shiiit Paul, hacker news has been screwed up since the beginning. Remember this video?

That video would show up on the front page about once a year, and is by one of your most popular members and commenters. The video is full of slander and straight up factual errors and even gets almost all of cryptography and network protocols wrong. It's probably one of the worst videos on security out there, yet, what did HN do?
Eat. It. Up. Nobody flagged that video, told tptacek it was bullshit, or bothered saying one damn thing about it other than cheering it on and laughing. You definitely didn't boot him off the site, and in fact gave him a top spot in your system. This is not how you tell people you don't like 'meanness'.
Over the years here and before I started commenting people called me a cocksucker, cock, asshole, douchebag, and every mean ass thing you can imagine. They do it to other people too, and I sure as hell don't see anyone getting flagged or kicked off. If you pick someone unpopular to insult you're totally allowed to be a dick here.
Paul, HN is in decline because you don't actually enforce your own rules. If you don't want people to be "mean" or talk like idiots then don't let mean and idiotic crap on the front page. Half the time, when one of my many clever ruthless jokes shows up on the front page I giggle. My jokes demonstrate what you've been allowing for years but only seem to care about now that it's insulting your own ethos of the "uber hacker scientist ruling the world":
You guys love cruelty and insult, I'm proof.
