Ye know when someone has no picture in his profiles it doesn't mean that they are fake accounts or prank accounts. Some of us are in sensitive positions and getting caught in such websites (which I do respect but most people don't) might cause some gossip and uncomfortable moments at the work. Hence, no profile picture uploaded. So, try to have a private message and get a number to take it from there to know each other more.

it isn't all about a profile picture!!!! don't be fouled by that.
