Lately I've been turning this over in my head a lot, because as a fan I have mixed feelings about sites like 'Realm Scans' getting hit with takedowns.
On the practical side publishers see these sites as direct competition: scans often post full chapters for free, sometimes hours or days before official releases in other regions, and that cuts into revenue streams that pay creators, translators, and print runs. Takedowns are a blunt but legal tool — DMCA notices or equivalent processes let rights-holders remove copies quickly, which helps stop a chapter from being mirrored across dozens of sites and indexed by search engines.
There's also the business angle that isn't glamorous: publishers sign exclusive deals with licensors, bookstores, and digital platforms, and they're contractually obliged to protect those rights. If they don't, partners who pay for distribution can walk. I
wish the industry sometimes moved faster on affordable, fast official releases, but I also understand why companies go after big scan aggregators — it's about protecting creators and keeping the system viable, even if it feels harsh as a fan.
