Things you don’t know about people who post things online:
1) If they use a real name, like on FB, whether that is actually their real name. You don’t ever know who you are actually talking to.
2) Their gender or sexual orientation.
3) Their politics, or whether they are just playing you by either agreeing/disagreeing.
4) Their wealth and/or specific investments.
5) What country they live in, or whether they are incarcerated.
6) Whether they are a person or a bot. People are getting fooled daily.
7) Whether they have hijacked the account of the person you think you are talking to.
8) Audio and video can be faked. So even with this “evidence” you cannot tell if a person did or said anything. Same thing with screenshots of brilliant trades.
We forget these limitations of the internet at our peril. When you think about the whole list of ways we can be deceived thanks to and specific to the internet, it’s hard not to consider only using it when you have to (work, trade, finance, etc.). Even worse, the internet has a tendency to attract narcissists, con artists, people with personality disorders, and compulsive liars because here is a space where you’ll never get caught. You can be anyone you want online, and that hasn’t changed in 30 years.
