It's a slow burn scan, similar to fraudsters who scam people on online dating sites. The scammer builds up a level of trust between the client and scammer by asking the client to do certain things, and the scammer does other things that build a level of trust for the client. A two way dialogue is started. The big hit comes later, maybe days or weeks, or even months down the line. Anyone who is not gullible would have disappeared off the radar quick. It is similar to gambling, and the gambler who cannot stop putting bets on, because that is what they hope to find: someone with a addictive personality who is not quick on the uptake. I cannot work out in total how this scam is operating - I admit - other than starting the dialogue, but that is all the scammer needs. It is no different to sales methods employed by car salesmen, who once they get a client interested, start to negotiate the price, give away add-ons such as a free warranty, gasoline, etc. The bigger picture is the sale of the already overpriced car whatever it takes, the big hit.
