@everyone
Due to a DMCA takedown notice, most anime extensions have been removed from the official extensions list.
Please note that there is nothing the mods can do against this situation.
I've heard there are mirrors but likely they won't be maintained (when AniWatch inevitably and intentionally breaks it again) since it was done by the Aniyomi dev
...who is pussying out on further development due to the DMCA notice. We have a fuck ton of Ani forks, but need someone to maintain the forks when these websites block Ani again because of it being a threat to ad revenue.
Aniyomi is a app for watching anime and reading manga (it is a fork of Tachiyomi which does the same but only for manga). It uses extensions for the sources it pulls anime/manga from (like aniwave for anime or mangadex for manga).
Aniyomi needs the extensions to use external sources, else it can be only used to watch/read anime/manga you already have on your phone
