No, but I'll maintain that identifying folks like that is dangerous and not a good idea.
What about the online registries of pedophiles and sex offenders? Is that dangerous and not a good idea? Or should parents not know if there is a pedophile in their neighborhood?
I understand it appeals to certain types.
What "types" might that be? It wouldn't be the types that have children, would it? You know, you can't trust those types.
