To be fair to In The Buff, I don't think this is a case of clients asking for past clients' particulars. In my case, I was advised by another member that Tiff (now Nina) offered up information about me that I had shared with her, and he didn't ask about me (since he doesn't know me).
I'm okay with SPs and hobbyists talking about past experiences in general terms, but providing PERB handles, names, ages, and professions of her previous client is probably stepping over a line. Personally, it didn't bother me too much but I can see how other gentlemen might have real concerns about that info being offered up.
