There's a thread running on another forum which draws attention to to the XHamster account of onhereforporn (xhamster.com/users/onhereforporn/photos). The assertion is that onhereforporn has been stealing images from the other place and posting them on his XHamster account. I've looked through and recognize a number of images as having come from AF (possibly, accepting that the model/photographer may have posted them elsewhere too).
Readers may wish to view onhereforporn's XHamster account and issue DCMA takedown notices.
