Well, my thoughts of this are:
FK COULD have: redirected the questions to the "Ask the Mfg." forum.
: PM'd responses, telling the person that they can't post possibly commercial messages, and possibly hoped that the individual woud let others know the "answer".
SHOULD have: had some verifiable proof, and after 40+ years in the business, I would have expected a company to be prepared for such questions. I'd be surprised if Mfg's like Ford didn't have some questions and expect proof before buying products to use on millions of $'s of cars.
I found that FK said 1 thing (ie. they have no test results as proof) then said another (Conducting a test for Japanese, had independent detailers test their products for them).
I DO think they were answering questions as "politely" as one may expect a vendor to.
I think they kept to their own line more than when registered as "TLL."
I have used some of their products and they do last a while. However, I haven't had any long enough to say whether or not they last much past 3 months (so far they are, but I don't *know* that they'll last a fourth).
David: I think he handled the task as per the rules. I think that if he would have redirected the thread/questions himself, then any other vendor who was shut down past/present/future may expect "warning shots/redirections" for all threads that may run afoul of the rules.
I think that unless there is a change in the rules, all vendors might expect similar actions.
I like vendor interaction, but if the rules say "no" then everybody should "play by the rules" or work to change the rules.
Just my thoughts.
