I'm guessing it's the proximity to Hollywood and the general behavior and values displayed by it's residents that puts the zap to their head and draws them in.
I mean, they're already a step closer to the limelight than the average Jane.
Remember, a lot of legit actresses have old nudes of themselves floating around from when they were trying to get a foot in the door.
That said, I say good luck to 'em for trying, but it's a longshot for sure.
