It's a website. It should cater for international users by default. Otherwise its just a bad business plan.
Once again, someone ignorant to how the world works. There are plenty of sites that IP block foreign addresses or prevent foreigners from signing up. Ever tried playing a Korean or Japanese game?
And, if they don't IP block, they require verification that you live in that country. Korean sites typically request a housing number which is pretty much the equivalent of a Social Security number. On top of that, a lot of sites will require you to put a cell phone number for that country as extra verification.
