OSINT off stuff like this includes

• IP addresses unless you’re using a VPN and periodically changing it up
• textual analysis if you ever comment
• interests if you ever subscribe or even regularly visit the same communities regularly (which opens a lot of doors)
• other accounts if you aren’t using single-purpose emails and handles

Privacy and social media are mutually exclusive. Find me a security expert that disagrees and I might change my mind. Right now you’re a random person on the internet, I’m a random person on the internet, and OSINT is real.

Privacy and social media are mutually exclusive. The ones you have linked are no exception. DD requires a phone number so I didn’t get any further. Minutiae has you taking photos and sending them to a centralized service. That’s not private. I don’t understand why you’d say that no is concerned about privacy with the implication that’s a bad thing then immediately recommend something as bad.
