Hey @meno, I have also asked this question several times! You video is spot on and the questions you have asked are totally valid. I agree with you that the people are so nice to each other because being an a**hole will have consequences which you wouldn't be able to afford unless you are a whale or have great influence.

Just like on Steemit where people are "Fake Nice", I have found that on other social media websites, people are "Fake Rude" . It's like their defense mechanism, most of the people I have met in real life are pretty calm & composed even though they are like some "Badass" on Facebook or Youtube. They troll their friends and be rude to strangers to look Cool. But in reality, either they are underconfident or soft as a marshmallow. :)

But all in all, over a period of time, being nice can be a good thing and people tend to replicate the same in their real life. Because they realize that you can earn much more money/respect by being a good person!

Cheers and have a "Real" nice day buddy!
