I suspect that they also troll as follows. Friend a business person with a professional looking profile with a picture. Interact a bit. Then go for the sale.

I guess that seems like to much work but in a sense it might yield a completely virgin market (business people traveling who would never think to read an ad or make pro active contact.) Almost like the bar honeypot.

Add: And be able to charge a premium rate because those contacted don't have any clue of the going rate and they have been enticed before they are able to pull back (not having any viable alternatives).
