It would be hard to take cards from people as that would be theft. It is also hard to know who for sure 100% is a bot. Also what exactly is a bot? Someone who lets a computer do everything? Someone who enters the moves himself but lets the computer tell him what to play? Someone that uses a cheat sheet on excel, someone like Bji1203 who is not a bot but is so good I can get many people to think he is a bot? Taking property away is not every good. Also this game has always been open to accepting and having bots buy cards and play. They can't ban bots now even if they wanted to do so.

That being said I agree as a community we should find something better to do.
