I originally chose to make my account on lemmy.world since all the content seemed to come from there. But I’ve since learned that I can fill my feed with stuff from any instance so it feels like it doesn’t actually matter if I’m on lemmy.world or not. At the same time, Lemmy.world seems to be frequently under attack so I’m wondering if I should change instance but have no idea what I should even be looking for when choosing.
Generally, yes, though technically it can happen to any instance with a small or single-person admin team. If an instance has multiple admins it is far less likely that it will one day just die.
