@mike @albertcardona Some instances already started defederation: https://fedipact.online/ (and everybody can block Threads personally, too).
But I'm not sure if Mastodon is secured against "Embrace, extend, and extinguish": https://en.wikipedia.org/wiki/Embrace,_extend,_and_extinguish
@NatureMC @albertcardona On one hand, that's the beauty of the #fediverse. People are free to federate or de-federate based on what they value and the kind of communities they want to participate in.
I would just caution that automatically walling entire groups of people off from each other out of fear could be self defeating for the Fediverse. There are many tools that can be used to prevent bad actors and bad behavior when it's seen. And more can be built to effectively federate moderation.
