My account (and my alts) were blocked recently (playing from SEA) as I had used VPN to circumvent the international cable issue.
They were unlocked after anonymous tickets to support, but now I am not sure if I want to risk another block / ban if they catch me a second time.
I literally just struggle through whatever dailies now (if I am even able to log in) and log off. Game is not playable, I had also paid for the VPN just for GW2.
I did ask support if I should continue to use VPN but did not get any conclusive advice.
