Okay, so, I've just done a review of the #moderation features in both #Lemmy and #kbin. I've written up a fuller report on the IFTAS matrix, but the tl;dr is: if you care about user safety, do not deploy either of these. They do not feature comprehensive or well built moderation tools, and you will not be able to effectively moderate instances running this software. You are better off waiting to deploy these once they mature more. Edit: removed user mentions to stop spamming them.
