KerryK The problem is that they announce the same thing from the platform, 'such and such is no longer a jw'.
I guess they just won't announce disassociated ones if it's no longer mandated you need to shun them.
I'm thinking this is how they're planning to get around the non shunning of disfellowshipped minors (which is how they can be legally sanctioned without question). They'll simply ensure all minors are made to disassociate themselves if they're caught committing a 'sin', instead of being DF.
