Someone in another thread suggested lemmy.zip and lemmy.today as having similar defederation policies as lemm.ee. That’s probably where I’ll go since I like being able to see pretty much all lemmy instances. Most of the ones that have been suggested in the replies to your post so far appear to defederate more than lemm.ee. I can’t tell for sure on the piefed instances since their /instances format is pretty different than lemmy’s.
