I play poker as my sole source of income, and I play at Full Tilt Poker and Pokerstars. I consider both to be very safe. Each site has recently offered increased security to players accounts.
To access my account requires my password + a random security code that is generated every 30 seconds from an app on my G1 Google phone.
Yes, it is possible for someone to be playing on multiple accounts at once; however, I would argue that the advantage to be gained from this activity is small in comparison to the advantage that established “grinders” have over new players because of their fundamental understanding of mathematics, statistics, and the game in general.
The sharks are the one’s you need to worry about, not the hackers. ’
There was a scandal involving a “superuser” account at Absolute Poker a while back – in which one individual who had access to the Poker Sites servers was able to see other players cards. Mind you – this was happening at nosebleed stakes – were talking hundreds of thousands of dollars. In my opinion, being concerned with hackers should not be your priority.
Your priority should be to improve your skill and knowledge of mathematics and poker in general – and to steer clear of the sharks – and no, I won’t reveal my screen name

gl to you.
