@stopthatgirl7 This seems like quite the lift and shift. Moving to a new platform would definitely split their user based. I would also thin that any form of aggressive defederation would split their user base as well. From what I can tell, there are not many (if any) fediverse platforms that have the level of moderation tools they they are looking for.
Unfortunately, It just looks like they are in a tight spot. One the could make or break that community.
