We have specifically refrained from doing that that on Lemmy.ml

In fact, there is an ongoing discussion on whether actual, patently false disinformation (climate change isn't real levels of patently false) should be removed outright or if leaving them up would be more valuable because the community on Lemmy.ml has been pretty good about calling out a lot of misinformation, the argument for that being that pointing out that it's wrong could be better than hiding it.

Edit: I see you're from Lemmygrad, and I also just want to mention that it's a different instance with different goals and its own rules, so what I say doesn't apply to that site, because I'm not an admin there.
