You cannot sit in more than once when playing a real game yet at GPOKR you can sit in multiple times at the same game (or Tourney) depending on how many internet connections you have access to. This is obvious when you see the medal tallies you realise who have access to more IP addresses than the honest players. This has become worse over the last 12 months. This is not guess work either I have seen many occasion where a player says they are going to log in with their other account(s) as they don't want to lose what they have gained and then later you see both these accounts playing at the same table. Until this problem is fixed you can only look on the Winners as Cheaters.
