To be fair he is doing something about it, he has found out who she is, where she really lives, spent time getting inside information from contacts and has posted a warning on here offering help to anyone else caught out. Yes he fucked up at first but at least he is trying to make amends.
That's very true. I am just speaking in general. In this day and age, where there are hundreds of prostitutes available in every city, I don't see why anyone would ever actually pay a deposit. The most reputable girls never ask for it. Only cash on arrival.
With the girl in your post, it's even more bizarre. She has only 7 feedback, including a warning that she is a scam artist, has been on AW for 2 years and she charges £90 an hour. That's enough of a red flag, IMO!
