I have not taken the time to look at the kind of software that is available today for poker players, but poker bots were widely available years ago and I do not see any reason why it should be any different now, as even if casinos make an effort to catch all the commercial poker bots available for purchase a person with enough coding and poker skills could create their own without too much of a problem.
After all even if poker is a complex game, at heart it is a game dealing with probabilities, and computers are incredibly efficient at crunching numbers allowing them with the right programming to be way better than the average poker player.
Yes, I know what you mean, but for now it seems that poker bots have been banned by some casinos for allowing online casinos some losses.
If casinos were trying to catch commercial poker bots it would be futile as there are still lots of poker bot makers selling them so casinos would have to make deals with those selling poker bots but this would cost a lot of money for these endeavors to be really successful.
It is true that that is why online poker games are difficult to win and only a few can win poker using the skills they have.
I really think those bots are partially responsible for the decrease on the popularity of poker, after all at the beginning of this century there was a huge interest on poker tournaments to the point those tournaments got good ratings which caused even the general public began to go crazy about poker.
However a stricter regulation combined with the development of those bots decreased the interest of the general public about poker, and it does not seems as if that interest is going to increase anytime soon.
