As I see it is really complicated and this problem is going on for weeks now, but no solution. Whales are not supposed to use Bots as they have already high SP and their posts will rank to the top of the trending page. Bots are supposed to be for Newbies and Minnows.

All posts that were upvoted by bots should be in the "promoted" section. That way the "Trending" section remains clean and we will have less problems. Good content will be visible to everyone.

It is very difficult to remove bots from the system now, as they became part of it. But some rules can be applied to avoid any kind of abuse.
