...they can't block people asking you where they can give you some money to thanks you.
Actually they can, and probably should. Soliciting or offering payments for something whose legal situation is unclear has the potential to become very complicated and I would certainly intervene if I saw something like that until I had clear guidance from the legal department.
Having considered this matter for a moment I think it's best that I close this discussion until I have an official answer. Please do not pre-empt it by bringing it up elsewhere; thanks. Sorry to those who just wish to discuss modding but as the subject has turned to monetisation I think it is best to wait for someone who can comment more authoritatively than I can.
