Suppose , I'm someone like Tesla car manufacturer and I want to promote my product.
One way to do it is to pay for advertising campaign, best writers will be hired and whole internet would be full of articles about my product.
Yet another way to do it is to get enough SP to make 20$ upvote for every post mentioning my product. I bet the resultat would be whole Internet full of posts about my product, and those posts would be written by the same best writers )
Why I still don't consider to use option 2 is an interesting question indeed )
