It was moderated, though. The thread was deleted, the shooter was banned, and multiple users cheering him on were banned.

More recently, the post that allegedly got Kiwi Farms removed from CloudFlare — a dubious bomb threat made by a previously inactive account — was removed from the site quicker than Facebook removed the Christchurch shooter's livestream.

Or, even more recently, a man live streamed himself shooting people for ~6 hours (https://www.bloomberg.com/news/articles/2022-09-08/police-ma...).

Facebook seems to be doing a poor job of moderating content.

Except that wasn't the end of it as the video was being reposted on Facebook for months. I remember reporting one instance if it and it took more than a day before it was removed.

And why should the content be removed?

It's a livestream of a racist gunman shooting actual people, together with his commentary. Real people are really being killed in that video. I'm not a fan of censorship, but this shouldn't be publicly available.

Well, it's just a video now. It was a live stream. It's awful what happened, but it's just footage documenting the event now. I understand why you wouldn't want it hosted on something like Facebook or Instagram or whatever, but to say it shouldn't be out there somewhere? What if someone wants to analyze the event, most big events don't have near that level of documentation. How is it different at this point (just the video of the event, not the event itself) from journalists documenting other awful things?
