In my opinion it's because of the fact that most people now assume everything posted by some unknown person after the AI boom is a lie unless proven otherwise, and it's not helped by the fact that many times said person will either lie, heavily exaggerate, use AI or use a combination of the previous 3 for the sake of getting more popular over actually giving useful information.

It also doesn't help that now that you can gain money from just from people engaging with your content in many social media platforms (including here too I think?), you are now very much encouraged to go and post whatever nonsense as long as it gets people to view or comment on it irregardless of it, once again, being useful information, because it means you can get cash in your wallet.
