By bots, you mean autopilot?
Realistically, as Fizzer has said autopilot shouldn't be able to beat even bad human players.
But, can it be banned? Is there a way to regulate it? If there is a way then I'd rather disallow them, but it's not something that's really even been discussed because it only came out the other day :S
You can't really ban it per se, I guess, but it seems unfair. We see the bots beating guys like Semice. I think we should just tell people not to, and if they do, shame on them.
