P.S., you can tell when a picture is faked by image quality around the slenderman versus the environment. This goes for all fake images, Slenderman or not. Another hint is if a picture of the person in the image is not centered in the middle of the image, as in to accent the image of the Slenderman in the background. Who takes a real picture with the main person in the photograph all the way on the left side of the image? :D
@R3APER(View Post) I think most pictures of slender man are supposed to be as if he was an unexpected occurance in the photo, as in, like he was noticed after the picture was taken. So it doesn't always mean pictures that have a peculiar focal point are fake, but I definately agree that all of the slender man ones are :P
I was there when it became popular, same with squid wards suicide, and even Pokemon black. its a lame creepy-pasta in my opinion one of my favorites is the moving comic as seen here: watch at your own discretion: http://comic.naver.com/webtoon/detail.nhn?titleId=350217&no=31&weekday=
