It's obvious that people are zooming in and seeing that, and as we all know photos are significantly blurry when zoomed in on. (unless by experts...) So that could just be matrixing, and just be a rock or something.
But I have mixed feelings on it. It looks quite clear so it has to be done by experts, and I dunno how they do it.
(I hate whoever locks yet another interesting thread, saying "locked cuz it mite sker 6 yeer oldz". It's most likely not really what people think it is.)
