Ok, I have met that girl in the past. And she was good, nice experience, and she looked great, much better than on those pictures. Later, I heard from another gentleman, who saw her after these kinds of ads started to appear, that it is her former ex trying to get at her. I guess he is succeeding, because given all this drama I won't see her again, no matter how good she was -- too much risk of unintended bad consequences.
PS When I saw her, it was at a decent hotel, SW are absolutely NOT my thing.
