How are they doing such posts ?

Hy friends
I am on make money online niche groups on facebook
And i see majority of people make some posts :informational ,give nice advices and inspirational ones
The thing its that i think they inspire from somewhere to make this posts and i cannot figure out from where they get inspiration
Someone has some ideas ? Thanks

People posy anything anywhere on facebook without thinking. Not everone is sm expert.

i think you can buy low price account and sell high price
