Another get this response when I tell them it was from TER, first they expressed being surprise and would said, they never placed posted the ad on TER.  It must be that so and so person where I place my real ad is at.

With advertising rates, hotels, flights, cabs, I'd bet they are trying to determine where their highest level and quality level of clients comes from. Sign of a sharp minded business woman.

We ask to see which sites are the most effective for advertising. Advertising is expensive!

If you are saying you saw the ad on TER, and then when asked for your handle, don't provide one you look suspicious.  For future reference, most ladies use between 3-6 different advertising sites.  I would give them the curteousy of telling them which site you have actually seen them on.  

If a provider has ads on 4 major sites, and only 2 seem to be effective, she can save herself money every month by not advertising with the additional 2.  Help the ladies out, and just answer the question.
