You miss the point - the bots only upvote because they believe the whales will. I saw a post today that had 31 votes but it only had a value of $4, because the whales were concentrating on noobs. So any bot voting that post in expectation it would perform the way previous ones by that writer did, would have been disappointed.

If the distribution is spread out far and wide, it becomes harder for a bot to predict, and will require the owner of the account to actually log in and read, to predict the value.
