With the recent scandal that rocked one major online poker site, many people are answering the safety of all online poker rooms. The truth is, the online gambling environment is sketchy at best, and one always runs the risk of being cheated when playing online.
One of the largest risks is people sharing their whole card information. The problem is, it is usually very hard to prove and up to the site operator to do anything about it. Given that it is in their best interest to keep it on the hush, or risk harming the integrity of the game, poker sites have often hidden the results of security investigations.
One thing is for sure, claiming you have been cheated is one thing, but the evidence is what matters. Take the recent Potripper scandal: It was not until the hands were returned and posted on YouTube did the offending site admit their system had been compromised, and the skeptics finally admit at the conventional wisdom preventing sites from ripping off its players was completely flawed.
After this whole scandal went down, it appeared to make sense that players wanting to prevent themselves from being cheated by colluding players or the site should arm themselves properly. Always record and histories and pay attention to the table. If you feel that players are colluding, quit and find another table.
While online players should think positive that cheaters like Potripper had to go to such levels to cheat the game, they should think negative that all the results of whatever investigation has been done are basically hidden from the players. For this reason, players should protect themselves as much as possible.
