It would also be nice if people were able to use cheats in a game against other people with cheats. It would be very enjoyable to watch battle of the bots in games and have people pit their programming skills against each other like this.
I seem to recall a certain game that had a shadowban system that just put all the cheaters in the same lobbies together. Might be misremembering that though.
I recall rumour that the relatively recent Fall Guys had such a system. A quick search seemingly shows confirmation from an official Twitter account.
