Do you see this man in Facebook ads all the time? Sometimes he offers cosmetic dentistry. Other times, he offers quick money, fast cash or any number of other services.

Now how about the cute girl below? Recognize this "college girl" from ads as well? She pops up all the time as the sweet, innocent teen but in reality she's just peddling her wares for whatever site she chooses.

Together, the both of them haunt our nightmares. There must be a reason why their pictures are used in so many Facebook advertisements. Who is this man? Why does it look like he's at a party and who got cropped out of the picture next to him?

Who is the girl with the backpack? Does she have a boyfriend? Are they serious or just, like, hanging out. These are things we need to know. The desire to find out who these people are is overwhelming and we can't do it alone.

We need your help. Be our Facebook detective and tell us if you know who these kids are or what their story is. If you have any information regarding their whereabouts, please don't hesitate to notify us.

Let the manhunt begin. Head over to our Facebook page now and comment on the post. Remember, we are stronger in numbers.
