WIth millions or billions of posts (and therefore millions and billions of users voting all the time) , the self upvoter wouldn't be able to have a significant impact on reward pool distribution, even with a linear model.. there would be too many other votes being cast.

I can't agree because there may be millions of people doing it (and there likely would if it works). Maybe they only earn a little bit each but it still adds up to a lot.
