I don't see how they can really stop cheaters until they do something like force businesses to post a unique verification code inside their store (or print on the receipt) that changes every day, and require that code to get any rewards.<p>With the way it's set up now, can't I just use my computer to send whatever HTTP request my iPhone sends, but with bogus coordinates?
My wife was complaining that she couldn't check in at any location yesterday because they all showed her being more than 100m away.<p>Most of the locations are marked by inaccurate GPS fixes in the first place.<p>This morning when I was using it, all the iPhone app was giving me was error messages. I think FourSquare might have just jumped off a cliff.
Oh oh. There goes growth (cheaters, and there are already many complaints from users that the new feature isn't working properly). Must've been scared by the Yelp lawsuits.
