Bid bots are a contract between you and the bot operator, they are not an inherent feature of this blockchain. As @captainklaus said, if people feel you are being disproportionately rewarded, they can return some of those rewards to the reward pool. It's your choice if you want to take that personally, but it's a bad idea, especially if those people are attempting to explain the mechanics to you.

I find it strange that you are so new to STEEM and were able to bid bot your first post, but don't understand the wider implications.
