I see the point, but at 200 participants paying $55 each, assuming a time valuation of 50 per hour, $350 out of 11000 is a small part of operational budget. Plus there are options to have evaluations done anonymously via the group of participants and setting a threshhold.
My main point was, the faq seems geared to prohibit only specific perceived abuses which is inherently subjective and arbitrary. I just take personal issue with the veneer of objectivity being used. I have no problem with subjective limitations if it reflects the will of the participating majority, but it should be explicit: we don't want XYZ to be able to do PQR etc. But LMN are ok.
