These are screenshots of women's Facebook pages with their indecent pictures superimposed on them.  The pictures were provided by an ex-boyfriend or someone else who knows the woman, or someone hacked into their email account or otherwise stole the pictures.  These are regularly posted on 4chan /b/.  It is not known why Christopher Poole permits this offensive conduct on his site.  The screenshot of this thread can be downloaded using this link.
