I think the best solution for the bid bots is to put a limit on the bids that accepted to prevent bidders going at a lose. But this will also decrease the bots' profit. But at least, you don't have unsatisfied customer.
Put a code or command to the bot not to accept any more bids when the vote values are on 1:1 ratio.
that we already do for a few months :) And people complain that they can't get a vote.
