They are free to have whatever kind of vibe they want, but yeah their rights should end where mine begin and all of that. Except they don’t, as even outside of their local communities they constantly violate the rules of other spaces, then their admins refuse to police them, even going so far as to be caught lying to the admins of other instances.
At that point, defederation remains the only available option, except even that is not the end of the matter when so many instances choose not to do that. Leaving the vast majority of the moderation burden to be placed upon the end user causes people to flee the Threadiverse like the 4chan-style place that we legitimately are.



No? Life is rarely binary.
For instance PieFed.zip both does not defederate with hexbear while at the same time not exposing new users to them unawares by placing a user-level block (which unlike Lemmy’s actually stops showing all content from those users) upon new account creation but then explains to the user how to remove that at any time. This makes interactions with them opt-in rather than have to discover it and be opt-out, so I consider it ideal. (Although I haven’t tested how that would show up to users browsing without an account - that might be a loophole.)
Or, a true opt-out solution could place a message underneath every post from that instance explaining how users are known to be combative, arguing in bad faith for “the dunk” and extremely likely to break your own instance’s rules and not conform to generally accepted standards of behavior. Something similar is done for Beehaw on PieFed.social, using that community’s own exact wording and linking to their ToS that differs greatly from the norm. However, I would wager that virtually all 3rd party apps would ignore this.
Defederation is not a first resort, it is rather the last one and for Lemmy, literally the only one provided when instance admins refuse to enforce both the rules of others and even their own stated ones (to keep trolling inside the community yet do not spread it to others WITHOUT CONSENT). Defederation from hexbear is not punitive - even members of hexbear have expressed a desire to defederate themselves from the outside world, to avoid all this drama - but rather protective of the wider Threadiverse overall, for new members to feel more comfortable joining us here.
