I see what you mean.
Actually I just did one better for that one on ninja...
Now, it simply will not let the round get overbid. If people send in after ninja is at -10% ROI according to the bot tracker it will refund them not letting them bid. This way the rounds do not get over bid. :)
Just started this couple days ago.
