moderation aint centralised, as it is limited to an instance. Want to see what your instances Mods have removed? Open that community from its host instance. Also don’t like the work your instance Mods and Admins do? Just switch instance and you are still part of the platform.
nah I just checked if a mod removes it it’s removed from federated instances too I just checked
grand, so the answer to your question “how is lemmy centralised” is “moderation and identity”, glad we had this chat
