Isn't the better question how will the APS respond when many of its members are banned like hundreds of professors and academics have been in the past?
In Wikipedia, it doesn't matter if you follow the rules, the policies, the standards, etc. when a person who is clearly putting in original research, plagiarism, vandalism, etc. isn't. Many times the regulars don't give a crap and would rather block the professor because the person doesn't fit in with their view of Wikiculture.
