https://defed.xyz No real surprises, but the list pales compared to Lemmygrad's still, they have 3x as many defeds.
Wrong link, but surprisingly useful, I'll have to pass it on.
Amazing comment, especially about defederation being the last resort.
Edit: jerboa and infinity are just being broken. I got some DIY HRT thread, saved it, but jerboa decided to not actually save it. Opened up the link in a browser and it's showing the correct thread.
