Jeremy Thank you again! OK, now I locked down all 12 items from the View Person submenu. But cover image, profile image and name are still visible. You can try it here: https://roundof.org/page/view-persons-profile?id=219

That's one of my test accounts. You'll see 3 items: a picture of a hanging train, a picture of a little plant seedling and the name of that profile: "Reicher Mann" (rich man). These 3 items should be hidden. I can't find out how to hide them.

There are no menus except for About, Terms, Privacy, Language, Design, Contact and Copyright. Those should all be visible from outside, so that's ok.
