When we’re advised that someone is SK, we normally change the access to the account to lock it off. We’ve been happy to amend calls shown on the reflector and database when asked. In previous cases I think family members requested this. I’m fairly sure one case both father and son were active.
e.g.
PA0WLB shows the call as PA0WLB/SK on the database
Messages from G4OWG show as G4OWG SK on this reflector.
