I didn't downvote but I think people really hate it when a web site doesn't work in their country for no good reason that they can see. So they're probably mad at you for suggesting a solution that involves allowing people only in certain countries to use a site. You might not have even been suggesting that... maybe you just meant one different login panel per country, which seems a bit silly to me. But downvoters vote on what they think they read, not what you think you wrote.
