One of the nice things about Fedi is that we get to make nuanced, local decisions about community norms. We're a leather bar, and .art is is welcome to decide they don't want our butts & bondage in their metaphorical backyard. That's OK!
But I do think it's worth keeping in mind that the social and statistical mechanisms of shared blocklists both erase the local nuance & historical context that goes into defederation decisions, and introduce new biases: whose perspective counts and how much.
