I'm not entirely sure how serious this website is.
It keeps track of anyone that has committed a felony in the US and shows where they live. The application itself isn't the amusing part. All the menus on the side seem like a joke.
From the site:
Safety starts with good information, even if it ends with a loaded .44 caliber pistol. While FelonSpy.com can’t help you get a gun, we can certainly help you figure out which direction to point it in
You can't make this stuff up.
