I wonder if we need some kind of middle ground like Twitter where you leave the content up, with a big banner saying "this content is bullshit and here is the evidence"?
While I agree that harmful information should probably be hidden so that impressionable people don't act on it, I also don't like non-experts being the arbiters of censorship.
Not to mention how much it puts on the shoulders of moderators to have to fact check every post/comment and find reliable sources to ensure false information isn't spread. It would likely be unsustainable without a lot of funding if the platform expands furrher over time.
Ideally the mod should've pinned a comment with the risks and a disclaimer about the serious ethical concerns. They instead deleted legitimate information.
