why would a valid ID be considered fraudulent

[legend018]

I notice that pretty much every Exchange I belong to doesn't accept my ID for one reason or another. Usually the reasons are vague and hard to tell if it's even related to my ID.
However, I just got a notice from LocalBitCoins stating it wasn't accepted because of reason: ID has been rejected as fraudulent.

I know it looks easy, but I really don't know what that means. It is truly a valid License of mine and is a drivers license. It's the only real ID I have.  I wonder what actually makes it fit this fraudulent description.  Confusing!
