Yes and no (as far as your question goes on advertising BDSM)...
The book is poorly written, badly edited, and the author knew literally nothing of BDSM or toy usage before the book - and didn't do her homework to find out the proper uses or safe procedures.
As a whole, the actual BDSM/Fetish world was (and still is) in a state of chaos - especially with naive women putting themselves in dangerous situations based on the suggestion of the book (ie: Craigslist ads "I'm new to this, totally submissive and looking for a Master" blah-blah-blah, infiltration of sites like FetLife only to find a world that's nothing like the book - and COMPLAIN about it, and even "Masters" and "Doms" showing up on vanilla dating sites asking around if people need training by a "real Master" etc.).
Thanks to this woman's moneybag husband who was just trying to make her happy by paying to privately publish her fan fiction, this thing has gone viral - and by doing so, has dragged down so many IQ levels with her writing style of a lovelorn pre-teen, criss-crossing American English with The Queen's English, and ridiculous repetition, both in actual words, as well as the same sex scene over, and over, and over, and... you get the gist.
Just my two cents, but I swear, if I ever see this woman, I'm probably going to beat her with her own book.
