I'm no fan of revenge porn either (god, that we have to write that???) but my step-daughter was bullied in high school and we reported one of the kids to the police; while we were there, he showed us a "site" that was organized by state and town, and was essentially a low-key version of Moore's site. The cop had her - by herself - look through to see if any of the pictures were hers, and I was shocked and stunned because my step daughter KNEW people whose photos were uploaded to that site (presumably without their consent).
My point is, this shit seems pretty prevalent, and so I would have thought he might have been more notorious as well. I've never heard of him myself, either, though I have heard of Charlotte Laws.
