In duplicate, these aren’t really factors. Once the hand is complete, the bidding and cards are known, and the limited nature of the problem means the requirement to have had information is more apparent than in other types of games. There are also many bridge players who essentially play at the current human maximum, and are easily classified as winners, and they have spoken about the cheating. Played card tracking in intermediate play might fit into the pattern you describe, though. At higher levels a misplay shouldn’t be happening often enough to be worth using this kind of software. I’m aware of the social dynamics you describe in online gaming, generally.
