@bitboxer The two left on the list don't seem to be terrible places if their stated policies are enforced, but a review of their local timelines shows their active users consistently interacting with users of extreme-right and MAP-oriented instances, so I have defederated with them out of an abundance of caution.
Pleroma has terrible moderation tools, and is clearly designed for "free speech" communities, as blocked instances don't seem to be strictly blocked on any instance I've investigated.
