Sorry Darren, I don't buy it about protecting the family group. It is the Privacy Level of the individual Profile that determines if data is to be shown or not and not the level of a linked family member. The Privacy Level of a Family Member has no bearing on this so the Privacy Level of a linked Family Profile should not automatically change when an Unlisted Profile is connected as a reflection of that Unlisted Profile.
I have already made my decision on what the Privacy Level of an existing Profile is, as is my prerogative as the Profile Manager, and it is not up to WikiTree to reset that level in a vicarious manner. An exception being those cases where a Public or Private Profile is set to Open by WikiTree to be within the rules where Profiles of people born over 150 years ago or who died over 100 years ago must be Open.
I set all of my Profiles to Open where that is an option so that others who may have data I do not have free reign to make changes or additions as they see fit and are proper. After all, this is a system built on a policy of collaboration. Closing Profiles by making editing harder demeans that policy. Especially where the person who was locked out after they made the edit thinks I'm a jerk for locking them out when I had nothing to do with it!!!! I am quite capable of being a jerk without anyone's help. LOL
