I am torn on the subject, although I may lean toward allowing vendors within the discussions only because of the confusion it would cause otherwise.
However, I would think it would be better if the interest of fair trade, etc. if the vendor STARTED the thread and gave some type of disclaimer and then followed up with if you have questions, etc.
Then, no matter where one is in the thread, you can always go back to the top and say, "Well at least he/she was up front about it.
