Oh wow!! I got that message too! I didn't respond because when I went to look at their profile they had nothing filled out and had no other posts. The message actually scared me. If they are a real person they would make posts. I actually got it twice. And they where not asking for friendship it sounded like they wanted a hook up or something. I may reply back via pm to see if they respond..I don't trust people who ask for my picture. I think it's weird I got the message twice.
