or it could just mean she was ALREADY identified and just signed in using a computer (which everyone obtains) or was playing on a friends/family/HERSELFS iDevice. It isn't hard finding a way to sign in using an identified account since there are so many ways of playing graal.
However, your very unlikely theory could be right which is why I would recommend staff to have 'check' on her account.
Also, didn't Hearts wipe out her whole database from the Euro center Database or something?
