In case you didn't know, there are about 1300 people on Experience Project that claim to sociopaths. I was surprised to see so many members. Out memberlist (besides puppets) can't be more than a quarter of that. I don't know much about this group, but there should be more diagnosed AsPDs there, based on numbers alone.
And then here's another elite group of 400+ people claiming to be "functioning psychopaths".
Apparently, they have the same problem as this place with an influx of wannabees.
