I would like to add that I am not referring to any specific individual or event in my post. I am posting to a general hypothetical. These mentioned actions, could be enacted against any member who violates a code of conduct in any way. Whether it is in the organization of a show or through an eBay auction. If you place the membership number next to your name while conducting business it could be that you are using the club as a tool for your business. The club than, I would think, would have some cause to take action if you violate any rules of the club.
