Just because you help some people doesn't necessarily equal a positive contribution for the entire community. I think about things on a more macro level and could really care less about the ROI of individual people. Long term sustainability and community health is the name of the game.
The issue with the above "factual information" is that it ignores the side effects that such bots have on newer users and uninterested parties. It makes it harder for them to get attention and it encourages them to sell out in order to progress. Sure a small group of minnows has benefitted from the provided service, but the overall collections of minnows as a whole has not.
Because it is more cost effective to delegate than to actually vote, the small fish community is not receiving as many shares as they used to as a large portion is being centralized to those that buy it. This prioritizes buyers of votes over non-buyers regardless of content.
As for "desperate animals", I guess I should stop using metaphors because some people take things too literally. Pet the sheep all you want, it does change the fact they are sheep begging for votes.
