I Live in Australia and i used a USA proxy to buy Star-wars The old Republic, and i am considering doing that to buy all my games from now on cause it's cheaper, how much trouble could i get in??? or would they just delete my account/ban it????
As far as deleting your account and or banning it. That would depend on EA and how well they plan on monitoring the incoming IPs to make sure they are within internally approved guidelines.
if you play it through a proxy then I doubt anything will happen other than high amounts of lag.
You lose any kind of leverage asking for assistance with the game though by spoofing your whereabouts and you may be unable to pay for the monthly subscription without a US based address and credit card from an authorized institution.
That being said, I hope it actually works out for you and good luck.
