alt Hacker NewsI'm sure there is some, but it's standard practice to keep at database of all your hands. I've sanity checked the winning regs (at my stakes) and they all make mistakes. I think it helps that in the US all the sites are geography based. It makes it harder and less financially viable to run a bot ring.
I don't know what a reg is but I would assume the first thing you do after you get your bot working is to add some imperfect play so that you don't get banned by the most trivial heuristics.
