Wouldn’t technically moving from hosting communities to having such a heavy involvement in their management be against the safe harbour protection?

Anecdotal: my neighbors entryway is recessed, and as so happens to be like 20 meters away from a window on the second floor of my house. There’s a ton of vegetation between us, but even if people are whispering there - I can hear it like they are right next to me. Especially when they are screaming at their kids to "be quiet"🫠.
It’s possible that your neighbor found some spot where sound from your house travels to. Do you normally take phone calls in a specific area of the house? Vs where you usually have guests over?

I’d imagine that would be offset by all the people who are redditing much less because most of the subs they frequent are private?
