Story time:
The first time I ever encountered an anon page, was back when Facebook just starting getting popular in my area, like 2009. Someone at my high school created a 'Burn Book' page and would post peoples pictures and write nasty things and even set up a Formspring account so people could anonymously suggest who to burn and what to say.
At first, people got a kick out of it because it was usually aimed at the 'popular' kids, who everyone loved to hate. The kids being picked on, didn't have a problem with it and we all assumed it was them behind it anyway.
A few weeks late, the page posted a picture of a girl and accused her of some pretty bad things, which led to her Mom posting on the page almost within the lines of what CSP is doing. Saying she's getting the cops involved, and posting inappropriate pictures of the people who were suspected to be behind the page, which wasn't really who was behind it (and that caused a whole bunch of more drama).
Kids at my school were angry at what this girls mom was posting and calling her immature and saying she needed to get a life, ect.
In the end, the cops and the school found out who it was and it was revealed who (a sophomore no one even knew). The girl deleted the page, her personal page, wrote apologies to everyone and was either suspended or her parents took her out for a semester (too many rumors to be sure). After all of that, students began to realize how cruel the page actually was and saw how much drama it caused and was glad the girl was outed and it was deleted.
Of course it sucked for the girl who was behind it because no one wanted to be her friend, people talked about her and was the butt of the jokes during homecoming skit night that year. But eventually, she came back to school, lived a normal life, people forgave her and people pretty much forgot about it.
Granted, this incident happened on a very different scale, but I'm with CSP. Would I have posted her phone number? No. Would I keep posting the names of who is behind the mean anon pages? Yes. They need to learn their lesson. You can have the pages deleted a million times, but the owner will just make a million and one pages.
