Points to be taken care of as soon as possible:
Refund of invalid bids, and also refunds of bids that crush the highest bid cap.
Issuing a warning to bots that do not follow the 5 points described here in this post.
An Orca, a dolphin, and a minnow should adopt a bot to take care of the bids submitted to it. Curate it in the timeframe of the bid submission and the time of the vote.
Comment voting should be banned for bots.
This actually sounds like a meaningful action plan. Thank you for taking the time to work through my extremely long post and pull out the next steps so succinctly!
