There are so many ways to beef up rumors. Word out of Bethel indeed - oh, that settles it then; it's official!
Fact is, JWs already have enough permission from the GB to pretty much "mark" anyone they personally disapprove of. I've known of JWs in good standing who have made personal decisions to mark other JWs in good standing based on personal justifications. In a religion such as Jehovah's Witnesses, the rank and file have shown themselves fully capable of carrying out all degrees of signalling disapproval of others.
