If it were just photoshopped in, why would they not have taken an extra 30 seconds and picked a photo of hands that matches the brightness and resolution of the phone, rather than use some crappy pixelated one that looks like it doesn't belong.
It seems more likely to me that they're trying to hide their identity than pass off the worst 'shop of all time.
That's an absurd reason. How anyone could believe that....
How does the pixaltion do anything to hide their identity? The hands are still quite visable; the pixelation does nothing to hide or mask. Do you also think the same reasoning was used to pixelate the left/upper left part of the image that is red and yellow but didn't touch any of the white areas?
Move along people. It's just some kid looking for attention with a poorly done fake.
