Among my points are that intimacy and scale are inherently at odds, and that human psychology prevents the public at scale of registering this. If there's a solution, it's going to be in the design, description (and marketing), operation, and regulation of those systems. This is a classic case of "personal responsibility" being a trope and cover for dodging corporate and engineering responsibility.

Evidence of this comes from the level and scale of information breaches: the US DoD, Department of State, Department of Justice, multiple states' attorneys general offices, the Russian Kremlin and military establishment generally (I have strong though as yet unsubstantiated belief that a key factor in Ukraine's success has been a near-total compromise of Russian communications channels). These are entities with a strong incentive to and capability for ensuring secure comms and data management ... and yet ... they're failing. The refugee family or abused mother or whistleblower ... stands little chance.

One of the criticisms of HN is that people are occasionally attacked for their expressed viewpoints, occasionally on-forum (though that's usually swiftly dealt with), more often off. I've seen some well-known and high-karma leaderboard profiles callously call for the death of entire groups of people. And there are sites which do kibbitz on "Orange Site" as they tend to call it, often criticizing its moderation or behaviours, but also conducting just the types of abuse you're describing.

HN also lacks some of the specific protections you describe. There's no private or limited spaces, direct messages, or similar mechanisms, by intent and design. There is the option of throwaway pseudonymous accounts, however, which helps somewhat.
