not at all related to membership status. Its not permitted when someone whos not a naxja sponsored vendor organizes a group buy and posts in the for sale section since the for sale section is for personal items and not for bulk items. Its ok to organize a group buy among the members especially when its a naxja sponsored vendor just don't organize it in the for sale section. IN regards to the patent stuff or copying someone else's designs, although we (socal bod) are not responsible for monitoring who's infringing on who's design, it really lies within the responsibility of the patent holder to protect their designs but we recommend avoiding any potential legal ramifications.
