AVN has the story; Erica Campbell's website explains her decision. Two things are particularly interesting: the sense that her charity work (animal rescue) was not enough, and the social network that emerged as she communicated with the men who paid for her pics. An excerpt below; for a different POV, including an intriguing comparison of working in porn with wearing a head scarf, check out this NOW discussion with Nina Hartley.

Here's Erica Campbell:

I love helping people, I love befriending people, I love animal rescue and rehab. I care a GREAT deal for my friends and family and ALWAYS do whatever I can to care for them and make sure that they are ok. For a long time I THOUGHT that I was doing the right thing.....and doing my personal best......well...I was wrong...dead wrong. . . .

The past few years have been very difficult for me. That is no secret to anyone that knows anything about me. I have been working my tail off to support myself, my farm, my rescues, my family, and the list goes on. No matter how hard I worked.....no matter how many people or creatures I helped I STILL had that void inside of my heart and my soul. Connecting with person after person through my site as REAL FRIENDS. I understood the loneliness of the people that I would talk to...because I myself was so lonely. The more I shot...the deeper my darkness got.....the more I understood the pain of others. My friends and my fan. There is ONE common thread to so many of us online here.....the need to be loved, accepted, cared for, the need to have SOMEONE understand you and connect with you. At the end of so many of these emails was that loneliness. SO many men have asked me what they were doing wrong, how to find a special girl like me for THEM. How to fill that "void" in their hearts...in their souls.
