But with that kind of money stream behind it, the mouse can go back to his investors and purchase a tiny mouse jetpack (or whatever the SEO equivalent is) to gain an advantage. If the cat learns to swat that, he'll come back with a toy car. Google is fairly active but eventually they give up: the mouse is a lot more motivated to get his cheese than the cat is to get the mouse. Google can penalize them 10 times in a row, but the 11th time, they win - and they essentially have the bankroll for infinite attempts.

Except the mouse only exists in the world because the cat choose to. Google doesn't have to list websites that are bad actors. There's nothing to Optimize if the search engine doesn't list you.
