I don't know who among those here have taken this survey.  I took it yesterday and my recommendation is to ignore it.

Let me explain:

The author writes:
"It is an original survey, the first of its kind in the world"

In private email with me, the author states:
"The questionnaire has been used with over 1,500 male clients prostitutes in the Western United States; in addition, some of the questions were used in Laumann's 1994 Chicago study (that one had a representative sample of over 2,000 adults) as well as with the population described above."

Those two statements are somewhat contradictory.  If it's an original survey, then how can it have been used before?  And, it's clearly not the first of its kind in the world - I took a similar survey some years ago (about 15) that was done by someone who was writing a book on the subject.  

Furthermore, in looking at the questions, many of them seem to be flawed, forcing the respondent to give inaccurate answers which will, eventually, lead to inaccurate results.  Garbage in = garbage out.  In my opinion, the questions show a lack of understanding of the hobby and possibly a lack of understanding of sexual activity in general.  

The stated goal of the research is to "help social scientists understand that the majority of hobbyists are not the disturbed or violent individuals that some have made them out to be".  I don't see how this goal can be accomplished with this survey.  In the first place, there were relatively few questions that seemed to address the issue.  In the second place, the assumption is that the people who are disturbed or violent individuals will take the survey and give accurate answers.  

The worst part about it, in my opinion, is that the entire concept is inherently flawed because I believe that the majority of males who are hobbyists do not participate on this board - I believe we represent a minority of the individuals in the hobby.

In my opinion, surveys like this are worthless and should be ignored.
