This is the issue.
How are new users meant to know what instances federate with which other instances and which are blocked? E.g. that Beehaw defederated with the Lemmy.world instances?
What (most) users want is to be able to see a sane set of defaults and from there make their own choices about what they do and don’t want to see. But by the time they’ve made an account. Subbed to a few communities etc there is a wall to leaving for another instance if you don’t like the way something is being run given there is no easy way to migrate your profile to another instance that may suit you better.
Now don’t get me wrong, online harassment sucks to put it lightly. Nobody should have to put up with it and it’s entirely (to reuse my previous example) beehaw’s right to block harassment causing instances, but that doesn’t make it any easier for new people trying to get into the lemmy ecosystem.
