Read on another site that this is the ad they used in the sting.

and that door in the hallway looks like some locked security door  
you don't see in motels!

I wrote a list of six red flags and then came to my senses and deleted it.  
Why help them make a better fake ad?

That alone would be enough to send me elsewhere.

The door is not open to the exterior hallway of a hotel/motel.  
The door is open to the hallway of a hotel room suite two room suite.
I'am not saying the ad is fake or was not used in sting.
I am just pointing out that it is the inside of a two room suite room in some hotel.
