Re: facebook and idiots....
"My wife is on FB. She's given up telling people they are passing shit by proving them wrong. They either ignore, as you said, or block her. Some people really, really do not want their personal little bubbles to be burst by a pin prick of reality".
I gave up trying to explain things to some folks years ago. I got into so many flame wars that I deleted my original FB account and even had to "play dead" for a while to make some people go away.
What really annoyed me was people spreading fake AMBER alerts - and these were friends in the UK. I tried to warn them that the alerts they were passing were fake, not even asking "How would you feel if someone took a picture of YOUR daughter and slapped it on one of these alerts ?" got the point across.
Even if you point people to an original source, they still won't believe you - I've had to explain the "Pacific Northwest Tree Octopus" hoax to several people over the years, and they still refuse to accept that they've been hoodwinked. Lesson NOT learned.
Who needs bots and AI when there's so much natural stupidity around ?
