So often I tell people something and they say “source” and I tell them why a source is not possible or spell out the exact limitations in data collection and then downvoted to oblivion with a pile-on of why this worldview is irrelevant
This is not a feature of these kind of websites, it is absolutely a flaw
I would say most of the world is not google-able, if you are doing anything of consequence that affects others politically or financially or legally.
