Some explanation, sorry I don’t know what you do and don’t know so forgive me if I go too far, perhaps someone else will learn too :3
0-Day is for scene (usually), basically the first release of pirated content. Like EDITH or CAKE (rip). In the comics sense they post to a usenet board, kinda like a super secret forum.
so the 0-Day Week bundle is a collection of all the 0-Day comics that were posted in that week to the usenet board
MaM and Geek are indexers that make it easier for people to find content to download. People post the 0-Day bundles there
You can settup an rss feed on these indexers to auto filter for these “0-Day Week” bundles. After you make the rss feed you can add it to your torrent client so it would automatically download any new weekly bundle.
Mylar is a comic book manager, like Sonarr/Radarr.
This settup will archive comics as they release week-by-week. More for people that want to host their own comic book server.
Only MaM is. They both “index” content though. Geek isn’t private, it’s just pay-to-use. I used “Indexer” just because it’s more general and still gets the point across
