I often encounter sites that basically assume you're living in America - many requiring you to have valid American credentials (state, zip, phonenumber, etc) to sign up. This is not only something that occurs on small sites, AOL is an example of one of the bigger sites doing it - (https://new.aol.com/freeaolweb/)Why is this? It seems to me that American companies are missing a lot of business this way. Is there a reason for it, or are American companies just ignoring the rest of the world?
