I agree with you, it's a scam. Women send me message, but never confirm a meeting. So I suspected a scam from long time.
So I do an experimentation, listen to that it's funny. I create a woman profile called "vaginalgirl". Few days ago, I receive an email from this "vaginalgirl". So they used my woman profile to send my a mail to my real profile. It's funny, right? What a scam!
