> Dear John,
> the problem is that even if the name of the depositing credit card and
> the account holderīs ID is the same, it still is no guarantee that
> he/she is the only person playing on that account. It takes several
> parameters to take into account to verify an account and sometimes new
> data proving a violation of our terms comes in late.
>
> We hereby confirm that we have received your ID-copy. However, besides
> from what our security system show it is clearly the same person playing
> on this account as well as on the connected account. There are obvious
> signs of previous experience and it would be more than a coincidence
> that you happen to play the exact same games and almost achieve the
> exact same scores.

> Your account will therefore remain blocked in accordance with clause 10
> in our terms and agreements.
>
> Your deposit has been refunded via PayPal and your winnings will be
> donated to Freeroll tournaments.
