Yeah that's another rule-of-thumb: Never say never or always, there's always an exception. I'm also fully aware of the irony of that whole sentence.

Yeah I get what you mean. Would be nice to have but I don't know how such an add-on would work in practice. I imagine that rather than filtering it out it would instead need to be something that adds a correction/context next to it. There's usually atleast a kernel of truth even in misinformation so simply just hiding it doesn't seem optimal either. An interesting point about free-speech I heard recently was that by silencing the fringes it leaves the rest of us ignorant to what views people hold as well as prevents us from hearing all the evidence that they're wrong. Generally I'm not against misinformation on places like Lemmy but what I do wish is that the top comment on each thread was the one providing nuance, context and correction. This place just doesn't encourage that. There's a set of accepted beliefs and viewpoints and anything going against that is just met with hostility. Cognitive dissonance is a powerful psychological phenomenom and people don't like their beliefs challenged.
