I am thinking of implementing an automated solution if the bot remains without bids, stuck at 100%, of just upvoting a random delagator post. At the moment, and I am not ashamed to admit it, if the bot is stuck at 100% with no bids, I just upvote a bot comment and so it becomes "unstuck". This is obviously not a long term solution, but it's better than the old uncapped version of giving a 1000% ROI vote.
It may be the fact that small bot market has reached a kind of saturation, we will see what happens when more and more bots cap their ROI.
