RE: Notice Under 17 U.S.C. § 1201 - Anti-Circumvention Violations - Hentai Manga and Doujinshi Piracy Circumvention Tools

1. INTRODUCTION AND LEGAL BASIS
 
This notice is submitted pursuant to the Digital Millennium Copyright Act, 17 U.S.C. § 1201, which prohibits the trafficking in devices or services that circumvent technological measures controlling access to copyrighted works. Remove Your Media LLC submits this notice as the authorized anti-piracy enforcement agent for FAKKU, LLC.

FAKKU, LLC is the largest English-language hentai manga publisher in the world, headquartered in [private], [private]. FAKKU holds exclusive worldwide English-language licensing rights through partnership agreements with major Japanese publishers including Wanimagazine, providing rights to over 300 tankōbon volumes and ongoing magazine titles such as Comic X-Eros, Comic Kairakuten, Comic Bavel, Girls forM, and Weekly Kairakuten. FAKKU's catalog includes works from over 400 contributing artists. In 2017, FAKKU acquired Kitty Media, further expanding its licensed content portfolio. 

The GitHub repositories identified below provide tools specifically designed to circumvent technical protection measures and facilitate unauthorized access to FAKKU copyrighted hentai manga and doujinshi content hosted on piracy sites.

2. TECHNOLOGICAL PROTECTION MEASURES 

FAKKU employs multiple technological protection measures to control access to its copyrighted hentai manga and doujinshi:

FAKKU Unlimited Subscription Service: Subscription-based access requiring user authentication, session management, and access controls on digital content.

FAKKU Digital Store: Individual purchase system with user authentication and download authorization requirements for permanent digital purchases. 

Geographic and Age Verification Controls: Access restrictions based on geographic location and age verification requirements for adult content compliance.

The piracy sites targeted by these circumvention tools ([private], [private], [private], [private], [private], [private], and others) host unauthorized copies of FAKKU-licensed manga that have been stripped of these protections. Many of these works were originally scanned and uploaded without authorization from FAKKU or its Japanese publishing partners. The GitHub tools provide automated scraping, parsing, and downloading capabilities that enable mass unauthorized access to this content, circumventing the need to authenticate through FAKKU's legitimate platform.

4. LEGAL ANALYSIS

Each identified repository violates 17 U.S.C. § 1201(a)(2) and/or § 1201(b)(1) because the tools:

(A) Are primarily designed or produced for the purpose of circumventing technological measures that effectively control access to FAKKU's copyrighted works, or circumventing protection afforded by technological measures that protect FAKKU's rights;

(B) Have only limited commercially significant purpose or use other than to circumvent such technological measures; and

(C) Are marketed by the persons who traffic in them for use in circumventing such technological measures.

The piracy sites these tools target (nhentai.net, e-hentai.org, exhentai.org, Hitomi.la, Pururin, Hentai2Read, etc.) host unauthorized copies of works that FAKKU has licensed exclusively for English-language distribution. By automating access to these piracy sites, the identified tools circumvent the need to obtain authorized access through FAKKU's legitimate subscription service or digital store, thereby circumventing FAKKU's technological protection measures.

5. PIRACY INFRASTRUCTURE TARGETED BY THESE TOOLS

The circumvention tools identified above specifically target the following piracy infrastructure hosting unauthorized FAKKU-licensed content:

[private] - One of the largest hentai manga piracy sites, hosting hundreds of thousands of unauthorized doujinshi including FAKKU-licensed works

[private] / [private] - Major hentai gallery aggregation sites with extensive archives of pirated manga and doujinshi

[private] - High-traffic piracy site hosting hentai manga, doujinshi, and related content

[private] - Hentai manga piracy site with extensive unauthorized doujinshi archives

 [private] - Streaming/reading site for pirated hentai manga

These sites collectively represent the primary distribution infrastructure for pirated hentai manga and doujinshi content, including works licensed by FAKKU from Japanese publishers.

6. STATEMENT OF GOOD FAITH

I have a good faith belief that the use of the identified repositories and their contents is not authorized by the copyright owner (FAKKU, LLC), its agent, or the law. The identified tools serve no substantial legitimate purpose other than to facilitate unauthorized access to copyrighted works.

7. STATEMENT OF ACCURACY

The information in this notification is accurate, and under penalty of perjury, I am authorized to act on behalf of FAKKU, LLC, the owner of exclusive rights that are being infringed by the trafficking in circumvention devices identified herein. 

8. REQUESTED ACTION

We respectfully request that GitHub:

1. Immediately disable public access to the identified repositories and their contents;

2. Remove all identified circumvention code, compiled applications, and related materials;

3. Notify the repository owners that their repositories have been disabled for violating 17 U.S.C. § 1201;

4. Preserve all records related to these repositories for potential litigation purposes; and

5. Take appropriate action under GitHub's repeat infringer policy against users who repeatedly host circumvention tools.
