I enjoy winding these scammers up. Called her and girl with strong East European accent answered, told her I was interested in seeing her blah blah blah but said that she did not sound very Thai. She assured me that she was. Having visited Thailand many many times I can speak some Thai so I gave her a fairly standard sentence asking how she was etc etc. Guess what? She did not reply . I said 'you don't understand your own language?' Suddenly she became 'only half Thai'. I asked if the other half was Romanian? There was some sort of mumbling in a foreign tongue at the other end of the phone and she hung up! What a surprise! Before she hung up I was able to suggest that she was a scammer pretending to be Thai.
Yes, it cost me a phonecall and a few minutes of my time but so what?
