I’m thinking of this that it becomes a challenge to admins of instances(servers) to deal malbots registering into these. If an admin fails to terminate or many registered malbots are found in his instance, poor server will be disjoined by Fediverse (sounds harsh).

Btw, I don’t like to call “instance” (I can’t imagine/picture of anything). I prefer calling “server” (I could imagine as separated CPUs connected by networks).
