Quoting scintilating:

HELP URSELF profiles etc who download the Photographs of Girls from their Profile and they get 5 cent per photograph. These photographs are later sent into Image Editors like Photoshop where they are morphed and superimposed on the images of Porn Stars. These people are so expert in this field that the photographs looks completely real and anyone can get deceived by generated images. These photographs are then used for multiple purposes like Printing in International Magazines, Uploading on paid Porn Sites and sometimes even blackmailing. And the post consequences are a known fact. So after knowing about this fact my advice to all sisters of my brothers here to please remove their photo's from Orkut,hi5 and other places and don't give the culprits a chance to do play around with You.
