The only reason, though, that this is necessary is due to public perception. A bunch of bots battling it out at an online poker table isn't by itself a concern for the online poker site - they get paid either way - the concern arises because the customers, the public, won't play if they perceive that bots are being used. (Bots allow collusion and stealing from other players - not stealing from the house)

Interesting article - I've seen enough good poker players to know that people can do exceptional things like this - I don't find the story that unbelievable.

(What I find more unbelievable is that someone with that much skill didn't have bots going on somewhere....)
