Until thats done, i think that could be done with an automoderator. E.g. iff a post title begins with [ONLYLOCAL] then trawl the comments every n minutes and remove all comments from nonlocal users. Maybe it would fall apart at scale? But im not sure. It would certainly be more performant as part of the software itself, but i do think its possible with an automod.

I dont think they defederated; i still see hexbear in the linked instances section. You can see it at the bottom of the page in the browser if you click the ‘instances’ link.

I feel like this is something where you, the admins, take priority. While i havent noticed much hate or spam from kbin.social (aside from random), if it is making enough impact that the admins dont have the resources (either time wise, emotion wise, or what have you) to do other admin things then i support you in defederating. Of course, i prefer to stay federated, but because you and the other admins and mods are doing the heavy lifting here i think your thoughts and feelings on this matter take priority.

I think goblincore is fairly different from the traditionall antisemitic goblins.
