Sounds like a average brit rumour

Sadly, these early examples of crowdsourced intelligence and social media investigations did not teach humanity anything…

Nothing British about it. This idiocy exists world over. Remember when the wrong guy got pointed to as the Boston marathon bomber? Or when someone shot up a pizza restaurant because of a rumour about paedophiles? Or when people stormed their nation's capital because someone who lost two popular votes in a row told them the election was rigged? Or remember when people, to this day, still try to claim a president of their nation wasn't actually from their nation and demanded he prove it, while also, to this day, claiming his wife is trans?

That’s sad as hell

We did it Reddit Australia humanity!

To their credit, every example you provided is from an Anglosphere country lol.

Specifically every example I gave is from the US, because I assumed that person was from there.

Yeah, they even left notes in English and Celtic.

>WHITE WOMAN! – There are fourteen armed men, partly White and partly Black, in search of you. Be cautious; and rush to them when you see them near you. Be particularly on the look out every dawn of morning, for it is then that the party are in hopes of rescuing you. The white settlement is towards the setting sun.

Shows just how dangerous preconceived notions are.
