It must be working cause I see many new fake ads popping up lately. Scammers figured out way to make money and not get into trouble.

...so I thought I would follow up.  Ended up in a conversation with someone who was more interested in stringing me along than screening or figuring out an appointment, and for whom English was not a first language. It came from a Wichita IP, not that that means much. And the last message I got, of course, was:
"OK. No problem, so you have to make a booking payment."
