Hi,
not sure if that should be integrated in BP itself? (see https://premium.wpmudev.org/forums/topic/re-hiding-a-site-from-the-blog-list-in-buddypress?replies=6#post-1329096)
– hiding blogs from BP sites list (a flag at the blog configuration)
– correct counting id user has no special role on the site (main site)
br, Eric
