Q u o t e: Don't you think it's going to be extremely easy for these Farmers to circumvent the Region locking? Just like they do in every other game with Region locking?
More than likely.
I cant really think of how to stop it. Only thing I can think of would be to require a US bank account, where a small deposit is made that you must then confirm, ie what paypal does. Obviously, that would alienate way too many buyers and is impractical.
