The comment thread where they claim responsibility: https://www.reddit.com/r/pussypassdenied/comments/4b85hi/vile_bitch_gets_exposed_by_herself_on_facebook/d17ezod?context=3

The content removed: http://imgur.com/gallery/Wd2nS

I have no idea why or how this was removed by them, but the post in question supposedly violated the content policy of reddit. Let's take a look at how it could have done so.

It's Illegal: clearly not

Is involuntary pornagraphy: No nudity of any kind here

Encourages or incites violence: No encouragement of violence in the post itself

Threatens, harasses, bullies or encourages others to do so: No threats, harassment, or bullying (at least on the part of the person taking the screenshots) and there is no encouragement to do so anywhere in the gallery.

Is personal and confidential information: This is the only point on which there might be a case. The imgur gallery should arguably have the face removed, but I think removal of the last name was sufficient for privacy concerns.

Impersonates someone in a misleading or deceptive manner: The poster doesn't seem to be impersonating anyone, and you can't even tell the identity of the person who uploaded the conversation (or the other participant)

Is Spam: Let's see, talking about a false rape allegation victim exposing the accuser in /r/pussypassdenied? That's not even close to spam.

The big question is, who is /u/PixyFreakingStix and why were they able to have the content removed?
