DMCA in recent years seems to be more aggressive with banning manga sites than anime sites.
DMCA taking down manga sites at a greater speed and with more ferocity than Anime, and even though Nyaa is great there are a lot of mangas that are not delivered in torrents and It's easier to find a torrent of a rare and unknown anime with at least 1 seed than of a manga.
As people said, the site was "DMCA purged" and lost part of its gallery, which, unfortunately, makes it one of the worst manga sites to read online nowadays, which is a shame I always visited it, but now all that's left is just a hollow body of what it once was.
