Digging into your clarifying comments further down, and what you’re describing isn’t social media but just a website people can post stuff on. Social media by its very nature is public, and when it’s public it becomes exploitable. I do think there’s an opening for a “landing page” of sorts where invited persons can easily share photos and updates with one another (I’ve seen it in the Enterprise repeatedly, though it never gains traction) like the 2010-era Facebook you describe, but it’d have to be something you (or someone in your circles) hosts for everyone if you want the privacy and utility without the ads, spam, and miscreants.
