When you shoot content, you get guys who want you to pass along their e-mail to the models. I never do, because if anything bad happened to the girl, I'd be wide open for a lawsuit.
I've also put some girls up on
http://www.onemodelplace.com with the responses coming to me first (in case I see an opportunity for another model as well), and they often get e-mails offering them money for traveling with some guy, or out and out sex offers, complete with "I have an 8-inch penis" and shit like that.
Good grief!
Some of these are from some obviously sad and pathetic guys, and some of them are creepy enough to possibly be predators.
I rarely pass any of these along unless they are just plain funny.
