Nah. Blahaj is also a safe space and well moderated without impinging on others enjoyment. Hexbear actively discourages other communities from participation, not with prejudice but with memes and childishness.

There are probably lots of great communities on hexbear but their bigger ones give a bad reputation to the instance in general. I've interacted with some great members in communities on non hexbear instances but for my instance at least, defederation was a net benefit.

If federation allows blocking communities, rather than instances in the future, that could change. However, currently it's only on a per user basis, so it becomes tiresome.
