@Homebrewandhacking @ajsadauskas @mekkaokereke if a majority of instance use whitelist moderation, the fediverse network will get weaker because smaller and one person instance will get sidelined, people will flock the big instance and you already have mastodon.social taking a large part of the fediverse plus threads that might take over an even larger part.
But I don't think having a few server using allow-list federation to protect black people would be an issue.
