Three identical messages shared for example by 3 people at the same time generate in people totally different reactions.
Example: Person 1 (less famous) or 2 (very good famous) are saying something, most people don't believe that and maybe even think it's bullshit. Few days later same message is shared by Elon Musk or a famous celebrity or politician or whatever, immediately the previous message become a true story, approved and liked, if no one told that before. Even if all three shared a bullshit, people still believe more what person 3 is saying, without put such thing in discussion.
Don't be like sheep #StopDieWelle and don't believe just because of the # of followers too!
