I think that is a very difficult cop-out to make to just say
"I hope ethical behavior prevails"
this is the internet and placing a dollar value next to a post influences greed.

More on topic of a solution, should users be able to upvote their own posts? Should there be a master thread for unethical behavior? Or if we're embracing botting, should there be a whalebot to show off large unethical profit margins?
