As someone who works in anti-fraud, would you be able to detect someone who was playing manually, but had a bot set up to tell them what to do (and then they would manually input the move)? Is that even illegal or against the rules?
keep in mind also that the whales in online poker are not high stakes players but "grinders"--folks who quit their day job to play a very disciplined style on low-stakes limit tables comprised mostly of beginners, and which requires multi-tabling (maybe 6 - 10 tables at once) 8 hours/day. So against that background, a bot playing 10 tables simultaneously for 10 hours each day, from a distance doesn't look so odd.
