Facebook Messages

I happened to open my Facebook messages today and found a whole bunch of random "emails" that I've never seen before. All from random people that don't have pictures, for instance:

Alan B*nder

Or this one, sent on Friday:

I wonder how many responses they actually get? Is it because I complain about being single too much?
