I agree with BluesBrother. I think with the right elders on a body in the right congregation (not referring to right as "correct" but as the ones who would react in the way I'm going to describe) they could view questions that clearly were designed to make other think carefully about what they believe as apostate teaching. I could see them counseling a publisher about asking others these kinds of questions (even if the publisher had been speaking to elders) to cease and desist, using Galatians 6:1 (" Brothers, even if a man takes a false step before he is aware of it, you who have spiritual qualifications try to readjust such a man in a spirit of mildness. But keep an eye on yourself,for fear you too may be tempted.") Then, if the publisher didn't stop, they might disfellowship on grounds of either "brazen conduct" or straight-up apostasy. If they choose to disfellowship for apostasy, that carries such a connotation with it that it would be unlikely to win an appeal, get the branch office to reverse, or even get reinstated, because a disfellowshipping for apostasy (note that this is different from disassocation voluntarily) carries in the minds of all elders who handle the matter later that the accused is deceptive, manipulative, and basically like Satan - looking to destroy individuals and the organization.
Not sure if those comments help but just wanted to provide some insider/elder observations from real-life experience.
