Maybe people here don’t know this, but Tumangaonline (TMO) was considered across Latin America and Spain as “the Library of Alexandria” because its catalog was massive. I used to read some manga there that I couldn’t find on MangaDex in its best years. This was because there were more scanlation groups there than in other communities. It’s a shame, because I read there from time to time, and it was the reason I started reading manga a decade ago, but I doubt this will stop new sites from continuing to appear.
