This is a feature that as far as i know lemmy does not have, so it might be worth it to checkout and support piefed, it will probably be useful if there are certain topics that are really relevant to you and you want to develop in depth knowledge of.
Is this using ActivityPub? I notice that the lead dev shares a username with a lemmy.world admin.
EDIT: yes it is I missed that it is already federated with Lemmy instances
The lead dev is Rimu - which isn’t on LW’s admin list.
