• It seems to accept any 2 letter combination for province (in Canada at least, I haven't tested other countries), regardless of whether they exist. It's a bit more picky on city, but it definitely will accept some random non-existent ones sometimes.

• if you have a valid address entered, and change your address to something invalid fast and hit submit before the javascript verifies it, it'll create the locations you entered even though they aren't valid. It doesn't swap your geolocation to that location when you do this, but it still creates the locations, which it shouldn't do
