Every single poster I've seen responding to articles on Lemmy and kbin from this site have been shitty, angry little pricks with regressive takes on everything. We need to block these trolls before they ruin engagement from well-reasoned humans.
I agree with @Drewski, defederation should be the last choice. Kbin does have an option where you can block whole domains, so if you'd prefer that, go here and click the block button: kbin.social/d/fanaticus.social
