Thank you for the reply.

"So basically you are taking away the chances for others to go visible"

So? If we both bid on an Ebay auction, I'm taking away your chance to get the item for cheaper. That's how a free market works. This is a good thing.

"Why not bid for whole 100% upvote"

This isn't possible the way Bellyrub works, and my goal is not to monopolize the bot nor prevent others from using it. My goal is to increase the curation rewards for my followers and increase visibility for my (extremely high quality) posts.

"have monopoly on bid based upvote bots."

Far from it, my friend. I've been using them for 3-4 days as an experiment so I can write about them from personal experience.

You still didn't answer my first question, how have you arbitrarily defined bidding in an auction as abuse? That is literally the whole point of an auction. You are just calling it abuse because you stand to gain from the results of doing so.
