Recently another one manga hosting site was downed by google personnel. The unofficial story is that their file hosting was located on google cloud servers and google nuked the content once it "found out" that it was used for "hosting illegal content".
Now some thoughts: Anime/manga community is, along gaming, is one of the latest bastions of cultural domains that didnt bend the knee to SJW bullshit completely. Could it be another agenda push by alphabet?
There is some tangential precedent for this if you are aware of Nintendo's long-going crusade against people pirating games (and acting hysterically in the face of people using their IPs without permission). It's a huge bitch to get 3ds roms right now because they somehow have pull with U.S. agencies to take down sites that anger them. They did a huge rom site purge in the past that nuked a bunch of normal sites, though it's been so long I can't be more specific.
I don't want to believe that japanese culture promotes being so retarded about IP law, but maybe there's a faction of hysterical busybodies that are rising to power over there.
You're right to be suspicious though, there is motive (financial and ideological) in removing a popular media form that many westerners are using to escape from constant propaganda and genuinely terrible media.
Just in case if you still want roms, there are a bunch on rutracker. The forum is in russian though, you may have to use a translation site.
I'll try it out sometime, thanks.
Also, username checks out.
