@TruthSandwich They could.. but that would expose their private IP to the server, exclude them from safety tools we have in place for exactly this scenario (subscriptions), add barriers to our own users even the good-actors (for examples those monitoring bad-actors) and tons of other reasons I have discussed in the past.

We do not defederate because doing so exposes our LGBTQ and other at-risk members of our community to harm, and we have discussed this as an instance many times in the past exactly how and why. We have at least 2 historic cases on our server where our federation policy has explicitly saved lives... Our users are adults, and respectful, they can have the power to decide for themselves what they see so long as they dont abuse that privilate.
