My family went through this in the 90's, and she was not allowed to give talks, go out in service and she was definitely marked as a talk was given about not dating an unbeliever. My father was a ministerial servant at the time was told that if he continued to let her live in the house while she dated a "worldly" person, he would be removed as a servant.
This resulted in her being put out of the house and she ultimately had to move in with the guy and his mother. The circuit overseer even came by our home to chastise my father about this with 2 other elders. So as far as I remember this has not always been the case.
