Rejecting a form is based on prior experience with the form and feedback from others who've played the form. So, if any forms have been tweeked, the PB has to be told or else any future feedback is based on faulty data. I've had a giant wasp before. I'm not going to play one every couple of months to see if they have been tweaked. So, unless I know they have and how, I'll always reject that form.
