There isn't that much incentive for bidbot operators to stop accepting bids after a certain point unfortunately. They're making money either way. It just bad for the people who've bid early. Like public companies they're selling a service but they're beholden to their sponsors. If it makes more money for their sponsors, why would they stop allowing bids that return a negative ROI?
