Check this out: it's a PDF of an affidavit offered in support of an arrest warrant in L'Affaire Spitzer. There have been several articles published on the Internet discussing whether Mrs. Spitzer should divorce Mr. Spitzer, but, in paragraph 6 of the affidavit, we learn that Emperor's Club V.I.P. is also known as "QAT Consulting Group, Inc." Mr. Spitzer may not have been seeking out prostitutes for the typical reason--he could have just been trying to get some advice in that area. And that's no reason to divorce somebody!
You really should read the affidavit. It's got some fascinating stuff. Paragraph 8 explains the alleged roles of the defendants in Emperor's Club V.I.P. (including pimp and madam). Paragraphs 24 and 25 talk a little about recruitment. I'm sure there's more, but I'm not going to do your dirty work for you. So if you have any interest in starting an international prostitution ring, here's your chance to see how it's done.
