ACR is one of the worst ones out there..

ACR also got caught with player farms with them telling each other what they have or had. For example if I was on the button and I was playing with you online as a horse I could be on a zoom call with you and I can tell you what I have and you can tell me what you have. ACR has now eliminated the ability for a player to look at their hole cards until it is their turn. There is a reshuffle feature that takes mucked cards and reshuffles them in the deck so mucked cards COULD show up again. Example if you are in UTG and you muck 4h9c those cards get reshuffled into the deck and even though it looks like you have hole cards infront of you these cards are not actually dealt to you until it is your turn and you could possibly get one of the mucked cards from the players before you. Knowing mucked cards is a minor edge but it's enough of an edge to make it 100% worth it. Take for example Black Jack in a casino, the house edge is about 0.5%-2%. This edge is what makes the game profitable for the casino. As a player by counting cards you are changing the odds ever so slightly, IE At a True 1 count the house has no edge 0% and at A true 2 count it give the player a 0.5% edge. That edge is enough to print money! Now its more than a 0.5% advantage because the delta between 2% and -0.5% is actually a 2.5% edge gain by the player but it is enough. So knowing a few folded hole cards might only give them a 1% advantage but it is enough to scew variance in your favour!
And with the nature of AI now there is no way to tell that it is AI. Of course the account needs to be linked to a real human but all it takes is an AI to tell you what to do and you do it. 100% impossible to prove. There is a reason why most poker apps require elevaled permissions on your computer (it's so it can see whats running in the background) and applications are logged and that info at any point can be seen by "the house". Hey this guy is winning 35% of the time, our math says a normal player should only be winning 15% of the time. Let's investigate what is running on their machine.. that is for greedy players that don't realize you cannot win that much but if you have a machine that can print money it is hard to not turn it on full and have it print 100 bills not slow and $5 bills! But if you program your AI with variance then it's undetectable to be honest. Play like a regular winning player but with just a slight 1% edge, the right amount of folds and stupid plays... Impossible to detect. Also you can run your Poker app in a VM and the AI would have access to the video stream of that VM so there is no way the poker app can see outside its container where your reall OS is running but it CAN tell it's running in a VM. More and more updates are coming that are locking this crap down. like ther eis no reason you need to run your Poker App in a VM so they will jsut ban it as say tuff luck if you have a legit reason to run it in a VM IE You are on Mac and they only have a windows client
Online poker is a shit show right now to be honest. I have about $500 sitting on WSOP.ca and i just have not played in 4 months becuase A) I have a new baby so I have not time but B) it's relly becuase I got so sick of hero calls and BS runouts that even varience cannot explain so it became more frustrating to play then it was fun. Some will say that is part of the game and at the stakes I am playing at players are so horrible that there is no way to tell that uneducated players will make these kinds of calls. To me this is the perfect cover for AI and a way to explain it... oh im just a dumb player and i made that call because dinner was ready and i wanted to quit.. These AI bots need to realize they are killing the fish they want to keep in the game. Like bleed me dry slowly LOL don't just stab me because you are only going to get to stab me once then I am gone! Right now it's only entertainment for me, somthing to do with the possiblity to win somthing basically like slots. I really hope it changes and it's not a change that is like "You must have a web cam on at all points so we can check to see if a real human is playing"
One person's rant about online.. take it for what it's worth.. not much :)
