I’m incredibly skeptical of the self-hosting email server claims. With the past 30 years of spam, most of the majors make it nigh impossible to do so. I know there are diehards out there that make it happen; it’s not as easy as it was 20 years ago though.

Edit: Very useful HN thread with multiple perspectives (not just my doom and gloom)

Note that the linked article answers your FOSS question.

This isn’t recent. This has been an ongoing thing for at least 20 years (if not longer; that’s just the earliest I remember having this convo). Yes, it cleans the wound by killing things but it also fucks up the healthy tissue around the wound (see other comments for a more scientific explanation). Having some in a medical kit is useful for other activities such as diluting with water for an ear rinse, diluting with water for various mouth stuff (rinse not swallow), and some skin treatments (again, diluting first).

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.
