A lot of the anime-related communities have consolidated over time to the ani.social instance. There are historical reasons for this (largely due to hostility from the ml admins), and if you want a brief history for just the general anime community, I previously wrote a post here.
That being said, the ani.social instance has been growing with new communities being added. Here are the more active ones:
General Communities
Series-Specific Communities
- !dungeonmeshi@ani.social - Delicious in Dungeon community
- !frieren@ani.social - Frieren: Beyond Journey’s End community
- !nokotan@ani.social - My Deer Friend Nokotan community (currently airing show)
- !dandadan@ani.social - Dan Da Dan community (show airs this fall)
- !dragonball@ani.social - Dragonball community
Misc.
- !vocaloid@ani.social - Very new community just started by @hisao@ani.social about vocaloids. Check it out!
- !vtubervids@ani.social - Community to discuss and share videos from and about vtubers
- !seiyuu@ani.social - Community about Japanese voice actors behind the scenes
So, as a moderator for !manga@ani.social, I have been trying to keep tabs on how this has been developing over on reddit (especially /r/manga).
I believe that if a publisher were to request content or posts to be removed, it would most likely be directed to the instance admin. In my community’s case, that would be @hitagi@ani.social. It would then be up to them whether to or how to remove the content. If it isn’t a formal DMCA or if they are in a jurisdiction not bound by the DMCA, then they could always choose not to take action. If they did decide to remove the content, then the next decision facing them would be how to remove it.
One option would be to “remove” it (no different than a community moderator removing things like spam). This action would federate out to other lemmy servers and remove it there as well. The other option that is available to instance admins is to “purge” it. This removes the content from the local server, but does not federate that removal out to other instances. So, the offending content would still be available to the rest of the fediverse since it was federated out and the publisher would have to go play whack-a-mole with every instance out there. The purge option would definitely be the malicious compliance route.
