Developers outside of the US cannot report reviews as bad reviews for stores other than their own country. If I'm a Canadian developer a user could simply load up my app and decide to put "This app makes my iPhone crash every time I load it" even if that were false it would destroy your sales and you have no recourse other than emailing random email addresses at Apple to hopefully get it removed. Allow us to view and purchase our competitors apps, allow us to report bad reviews for all countries.
