Good to know. I had accidentally created multiple accounts for myself around '05 or so and was really surprised by it. Iirc back then they also required separate accounts per-country, but I could be wrong about that.
I don't think they require separate accounts per-country, but my only experience is with .com and .ca. They might do the accounts on a per-realm basis (North America, Far East, Europe, etc.) rather than strictly per-country.
