For anyone who's confused, here's why this is happening: Copyright dictates that photographs are protected from the moment they're created, and that the owner of the work is generally the photographer. After photographing famous people, the paparazzi sell their images to photo agencies who then circulate them to the media for a fee. Any time you see a paparazzi photo of a celebrity either on a website or in a magazine, it’s because the outlet has “licensed” the image by paying for it. Therefore, posting a paparazzi image without a credit, license or permission from the owner not only results in copyright infringement but loss of earnings for the photo agency, since images lose their value once shared to millions of Instagram followers for free.
