But you have to consider those that use the bot that "do" give out good quality content that doesn't get exposures. As time goes by, it will be harder for good content creator to show on the trending/hot list. If that's the case, people will tend to lose hope on posting on the site. They might ask, why should I post if my great quality content isn't getting the upvotes it suppose to have. They might also think that, other oddly and not so much good quality content are up there and getting their over valued upvotes. My two cents on the bots. Of course, your point of view is also good to consider.

Bots are tools to be utilized, use it to our advantage and if not performing that's when we dump it.
