Yeah. If you’re on a public forum accessible to anyone, which the whole fediverse is, then you should never assume privacy.
Honestly transparency in this regard would be better - they’re already visible to much of the community, so they might as well be visible to everyone.
It’s a weakness in the sense that there are times this place turns into a straight-up echo chamber…
But when there is actual debate going on, it tends to be a lot more civil than on other sites (most of the time)
