Most bid bot buys net you a loss.

I doubt that, especially considering the people who frontrun the bots and all the fools who jump in after the big vote because they don't realize what is happening and they think it will earn them curation rewards. I thought the exposure/marketing justification was there for the vast majority to justify cheating, not that they really want the exposure, why? Because there was almost always a lack of engagement from the buyers under their posts. In short, they buy because it does return a hefty profit, especially if you factor in the lecherous frontrunners and the idiots that pile on, comment or whatnot.
