Agreed. As an Aussie, I fall into the European region according to SE but even if they wanted to go by only the countries that are really part of Europe, they're not doing that either. It would be good if they could stop calling them EU contests if that doesn't properly define them.
Honestly though, I get mails or approached in public regularly about raffles and other competitions that offer prizes with real dollar values (often asking me to buy $15-20 tickets for a chance to win some big house or something), so having another company say that they can't do that for legal reasons is a little frustrating...
In the end, there's nothing I can do about it (unless SE wants to share exactly what sort of legal problems they have in bringing these competitions to other parts of the world, then we can actually approach our politicians with something more appropriate than "Get out of SE's way!") so I'll just wish those lucky people (who happened to be born on a pin head) that can participate all the best of luck and fun. If nothing else, I can still enjoy the competition from the wayside ^_^
