I've seen "answers" which are simply factually wrong, and have commented on those "answers" to correct it, even providing the proof of the facts, but the posters are simply refusing.
I've tried suggesting edits, but they've all been rejected with as reason "This edit deviates from the original intent of the post. Even edits that must make drastic changes should strive to preserve the goals of the post's owner." which is, frankly, ridiculous. If someone were to post 1+1=3 (fictional example, obviously), and I suggest an edit to correct it or suggest an edit which adds a note that this is factually wrong, then of course my edit goes against the intent of the poster who is trying to push the fantasy that 1+1=3.
I've tried flagging the "answer", providing proof that the statement is indeed factually wrong, and ask for a correction or removal, but then I get rejected too, with the message "declined - flags should not be used to indicate technical inaccuracies, or an altogether wrong answer".
What else is there to do? Commenting, editing, flagging, all of them lead to nothing!
I've read downvoting but that's a ridiculously naive option. The post has several upvotes already because the "answer" looks complex (creates fake trustworthiness) and is popular in certain niche groups (think flat earth groups, but less obviously wrong).
Is there no adequate way to deal with such blatant lies and factually wrong answers?
That's very depressing for a site which is all about spreading information and an unacceptable blemish on its reliability.
Without the proper tools to make sure that stated claims are indeed correct this place will devolve in a site for tinfoil opinions and fantasies and not actual; objective facts.
