Default instance blocks should largely replace defederation
Since what content users might want to see is quite unlikely to match which servers the admins tolerate, choosing instance on the Fediverse can be quite complicated, which is inconvenient and off-putting for new users.
For this reason, and simply that the Fediverse is stronger united, I believe defederation should ideally be reserved for illegal content and extreme cases. If Fediverse platforms would allow instances to simply block the rest for users by default, the user experience would be the same, unless they decide otherwise.
(Edit!: can’t you just block users who you don’t like what they have to say no matter how mild?)
I don’t see why a couple of peeps other users get offended by because they have a different opinion but aren’t bein outright harming/threatening/other Xtreme actions, should lead to those peeps’ instances being blocked and or defederated. looks so pathetically bad when that happens and can also turn off new users
