I know of two unbaptized young guys on separate occasions, both around 13 or 14, who were announced to the congregation as "disassociated".
One had taken a summer job with the Cadets.
The other - an elder's son - was just the usual rebellious teen.
They never "reversed" the announcements once the policy changed that applied DAing to baptized people who voluntarily "resigned" from the organization.
