Maybe there's some misunderstanding here. I'm saying it doesn't make sense to compare it to a house because of the exposed public nature of it, not based on public or private ownership of it. The house argument applies to a private space where one has sanctity, security, and privacy. It would be laughable to argue it for an open field even if you do own the plot.
Lemmy servers are more like those empty field plots than a house you'd expect safety and privacy from, see where I'm getting at here? If not that's okay. I'm used to not being understood by people, either unintentionally or intentionally.
If that's the case why don't the other light green regions also have hentai, from the top it seems like you need a lot of radiation to get hentai otherwise Sweden would be covered in red hentai regions.
