If your relationship status is blank on your Facebook page, there is a new feature that spills the beans to everyone that just wants to know.

If you go to a person's profile and see that they haven't filled in their relationship status, now you'll also see a brand new button they just added that says "Ask."

When you click on it, it sends the person a message asking them to tell you whether they're single or in a relationship or whatever.

It sounds like it could be a decent new way to very casually flirt with someone . . . kind of like the poke used to be. But like everything on Facebook, it's really just another way for them to get their hands on as much of your personal info as they possibly can.

If someone presses the "Ask" button on your profile and you respond that you're single, Facebook now knows that and they can target ads at you better.
