I have started reporting weird bids from robots (not carding, I would end up doing only that) getting no feedback from BBO. Without ignoring the acknowledgements given in the help section for Gib playing, I cannot prevent myself to think that weird Gib bidding (often shooting a bullet in your own feet) is routinely programed in the AI to encourage you to put another 1.25 USD in the machine, striving to achieve your next level of master point. This is getting very frustrating bridge experience on the long term.
