Hi Keri...
Well to be honest, considering the email I got from BOL that clearly states that one player may only have 1 account on Chico network, I really don't see how this is hard to determine, players clearly used some method of deception against either Tiger or BOL and you should email those rooms and tell them about the issue and ask them to confirm if the players used different names.... That said I guess if there is nothing you can do I will just say thanks again for the league etc.... But I really think this ought to be resolved for future seasons, as it is very similar to an American player all of a sudden playing on William Hill - it is against the regulations and should be strongly discouraged and in my opinion sanctioned too, as I for one was some 7-10 tournaments at a disadvantaged against these players, who are European like me, so unfair is unfair and I would like to see future seasons avoid such issues for the sake of all players.
Also, being able to access a player's usernames somewhere on the site would be nice, as now it is really hard to know who is who and this would make things more transparent.
To make myself clear I don't mean to jump at anyones throat here, I just wanted to turn your attention to what I think is a not that small of an issue, as it gives players who have BOL accounts (somehow) much more of a chance to win the league and get another win or top 3 score that other guys don't get to play for. What is more, don't think this is at all pokervip's fault, but rather that some players are abusing the league to their advantage and I'm sure we all hate to see such things happening.
Best regards and keep doing the work you are doing, we are all appreciative of it.
