I just posted about this on !fediverse@lemmy.world, but figured 'd share it here as well. :)
I'm the author of lemmyverse.net and I've recently been working on a new moderation tool called Lemmy Modder. https://modder.lemmyverse.net/
Currently, it supports user registration/approvals and content report management. I offer it either as a hosted app (which is currently only compatible with Lemmy 0.18 instances) or a package that you can run alongside your Lemmy instance (using Docker-Compose)
Feel free to give it a go and send any feedback my way :) https://github.com/tgxn/lemmy-modder
Edit for a note: This tool does not save, proxy or store any of your user credentials or data to me, it is only ever stored locally in your browser. I also do not use any website tracking tools. ๐
