There will still be the issue of each one not being privy to the sections of the board not normally available to them. (Provider = Men Only Portion of the board vs. Hobbyist = Ladies Only Portion of the Board)
It would be best to inform the Staff of the relationship at the time of registration. That way it's out in the open, then there are no surprises. If the SO joins in a clandestine manner, Staff will have no idea of who they are, until an issue arises. Then the questions will arrive fast and furious.
It would difficult to know that a review submitted on the Provider is not to be considered for PA Credit, unless the SO reveals himself to the Staff.
The answers provided are based on my understanding of the Guidelines. To receive a definitive answer to your quests, you would be best served to contact Web Support and present the situation/scenario to them directly.
