ACLs - privacy settings - GDPR issues

Hi,

Why is that some items are still visible to guests when a user's privacy is all set to a "minimum" privacy setting to registered users?

From Page views:
- Stream items from any user
- Followers are all listed and linked
- Comments are visible to anyone
- ... and more ...

From Group views:
- Stream items from any user is visible for guests
- Members list, all are listed and linked
- Comments are visible to anyone
- ... and more ...

Same is true for Events ...

A conflict happens with "Public" setting of Groups, Pages, Events, ...
These should also follow the correct privacy settings from both user's own settings and user profile settings.

Shouldn't there be a Viewing Permission Setting in the category creation for all these (Pages, Groups, Events, ...)
- ONLY display owner/administrator activities for guests
- FULLY respect users privacy settings
- Follow Profile Type privacy settings

Plus ...

When moving the mouse over a user name in stream it displays: Access to this profile has been restricted for privacy reasons, no image is displayed in mini header
( - But because of privacy settings user activity should just not be displayed at first ! )
Why then can we also click on the username and access his profile, display his picture and profile banner when they are hidden by restrictions in the hovered mini header ? Where is the logic?
Is the full privacy really respected?
- Should there be a more restrictive Viewing Permission for user to not be displayed/visible at all ?

I am looking forward to reading your explanations and understand your logic about these...
