It's looking really bad, looking up almost any series to find those scamy sites leads to literally hundreds of dmca'd notices and almost or no sites at all where you can freely read manga anymore, wish there was something we could do to help out and protect the site but there's nothing really, rip I guess
One good thing about about about shitty manga sites is that they tend to mirror each other, so a lot of mangas that get dmca can be found somewhere, problem is that Google seems to hide many of them even if they don't remove series, betting a dmca is enough for Google to hide them
I'm not aware of any library export tools.
If no one creates one within the next week or so, I will do it myself.
We don't know how far this will go, it's clear at least Square-Enix, Kodansha and Shueisha might try dmca every single thing from them here on Mangadex and in other sites.
So here a question, worst case scenario, could Mangadex work similar to mangaupdates for the removed series? We know what was removed is probably removed forever, might or not continue receiving new chapters, we don't know yet how that will go, I do know I saw new uploads but from chapters that didn't get dmca, so I guess they technically don't count for the dmca.
Anyway, my point is, for stuff removed we'll get a list of all chapters that were uploaded, just to know what was here, if a ongoing series receives a new chapter but don't get uploaded here, could we still get a notification in our feed? Just so we know a new chapter is out.
Worst case scenario Mangadex could still keep us up to date to what is translated but we go somewhere else to find the chapters, like torrent.
