Yeah so, I have last been online around 2 days after the in game gametime token got introduced in EU servers. Today tried to log on my main account and got the same message that everyone else has been posting. Just a guess but they might monitor accounts using in game money for subscription. Kinda strange that I haven't used these services in around 2 weeks but still got hammered. Please be very careful on these times. EDIT: btw this is the first of my accounts being banned and the only one that is currently active. Also the only one which I have used gold to buy gametime (official AH token).
