Actually, you know guys, I'm a first hand encounter of people using my pictures, so yeah. I mean, I kind of believe Stocking is still real, but that's because I'm a nice person, lol.
In terms of my experience; people have stolen mine and my girlfriends pictures and put them as their own facebook pictures and made fake profiles and stuff, people on chatango have stolen my pictures a lot of time as well.
I found my picture on 4chan once or twice as well, one of the times it was an ad for a gay love chatroom, lol.
