What can you do when you think people cheat?

this is how i handled it (mail to pokerstars support):

hello support,

is there any possibility to check this guy out if he using any stuff that helps him to see my holecards or any other cheatstuff!!! i dont know how to find the right words, i think its rigged what hes doing! he playes so bad and doing stuff ive never seen before in my life and hes winning all the time! So after now like 50k hands ive seen of him i dont get it in my head, HOW?to give 2 examples:

the board is K1083 with 2 spades, we raised preflop and there are 6bb in the pot with 3 players, flop we all check!now i bet all in because they both had like 20bb! XYZ calls me with 18bb, the other guy folds, he shows J1099 ( i had AAQ2 with the nutflushdraw)

1) i mean he played so many hands of this game and this is not the first time i see him making a call that is a 100% NO GO, but he binks a Q on the river and wins (does he know what the river comes down)
2) the point is not that i lost a hand i was massiv favorite, the point is feel like, wtf is he doing? even if hes a fish, why he doesnt go all in on the flop where everyone checks? that would make even a little sense! can he see the rivercard first after turn is dealt? WHAT IS HE DOING?
3) its completly weird how the hand runs, so i feel there must be something wrong! and its just one of few i picked out!

BSP 2: hes shoving button 100bb 3handed and i sit with AK34 in an hi low no limit game.
1) why is he shoving? does he know i have a hand to call him and he beats me?
2) my tracker gives me informations about how often he is openshoving with 40bb+ and this is like 2%
3) how is it then possible that he shove 10times over 40bb into my bigblind (i have a hand to call him) in less than 200 hands? i know its possible that hes crasy or stuff but its looking realy weird what hes doing and that over so many hands, if i wouldnt feel there is something wrong i wouldnt write you this stuff, i play poker for more than 4 years and i´ve never seen something before!!!

I hope you can help me with this.kuhns89

I COULD LIST UP HUNDREDS OF HANDS I THINK ITS TOTALY WEIRD WHAT GOES ON HERE... HERE THE ANSWER OF SUPPORT:

Hello,

Thank you for sharing your concern about the security of hole card information.

Please first allow us to explain that the program installed on your computer cannot be hacked to show the actual hole cards of other players, or the cards yet to come. This information is not actually transmitted from our servers until the instant the information needs to be shown on screen, and is not even accessible by the client software before this time. It is simply not available to your PC.

Furthermore, PokerStars can confirm that no player is able to get information from the actual PokerStars server on what cards are coming, what other players' cards are, or is able to manipulate the deal. To this date, with all the sensing devices we have in place, we have never been given any indication or evidence that such an attempt has been made or that it is possible that any program to do so exists.

We are aware that there are some programs advertised on the internet that claim to make it possible to see other players' cards. We have investigated many of these programs, and have not found any that do what they claim to do. Some of them are actually malware, programs that compromise the security of whoever installs the software. But mostly they are simply scams; attempts to steal money from people who believe incorrectly that they will get a competitive edge. In truth, they do not compromise PokerStars security.

In addition we have dealt tens of billions of hands and have never had cause to suspect that our shuffle software has been hacked. Each card is randomly selected and has no connection to the next card.

Please note also, that PokerStars operates state-of-the-art defence systems to detect and protect our games from hackers.

For details, please see our site integrity web page:

However, it is possible for *your* PC to have malicious software installed on it - either a virus or some other sort of malware. If you believe that this has happened, we can give you some advice on how to secure your PC however we encourage you to consult a local computer security expert to inspect your PC and to take appropriate steps.

Of course, if you have further information that you would like us to respond to in greater detail, or if you have any other questions, please feel free to write back any time.
