I would fully agree that other internet protocols are much better suited to information not meant to be broadcast publicly.

Civility is great, and should be highly encouraged. That’s largely why I like Lemmy. Each instance can guide its community in line with its values, whatever those may be, block offenders, and generally forge the space it wishes.

However, I think Besse’s comments on setting the correct expectations in the public sphere are worth considering.

For a different internet example: all the messages I send in any chatroom on an IRC server will inevitably be logged by someone, especially in popular rooms. Any assumption to the contrary would be naïve, and demanding that people not keep a log any of my publicly broadcast messages would be laughed at by the operators. It’s a public space, and sending anything to that space necessarily means I forgo my ability to control who sees, aggregates, archives, or shares that information. My choice to put the information into that space is the opt-in mechanism, just how books or interviews do the same offline in print.

It’s not so much the protocol as it is how making things public fundamentally works.
