That works if the instance openly expresses a general policy on defederating , and then adheres to their own policy. Based on the whole pre-emptive threads defederation that many other instances took part in, but lemmy.world did not, it seemed like they were aiming to be a very open instance - their stated reason for not cutting ties with threads was to have a wait and see approach and actually give them a chance before assuming it will be a problem (and it’s not like meta has a stellar track record either). Now with hexbear they are taking an immediate defederation, no chances approach. It would be nice to get some clarity on the general criteria for pre-emptive and reactive defederation in order to make those home instance decisions.
