    これらの出来事により、DMMは複数の事業ユニットを閉鎖せざるを得なくなり、分散型技術(特に分散型ソーシャル)への取り組みも大きく前進させることが難しくなりました。

    一方で、DMMは影響を受けた顧客への補償や、関係する株主への資金返還をすべて実施するなど、非常に責任ある対応を取りました。亀山氏は顧客および事業上の責任を最優先にし、言葉に責任を持つ人物です。

    まるでpixivがFediverseにもたらした大きな影響のように、私たちはDMMがそれ以上に大きく、かつMetaのThreadsと比べても、よりフレンドリーな形で貢献してくれることを期待していました。

    しかし、2024年6月にDMMは北朝鮮系ハッカーによって約482億円(約3億ドル)の被害を受けました。その数ヶ月後の2025年には、私自身も約400万ドルのハッキング被害に遭いました。

    幸いにも、これらの出来事は私個人には大きな影響を与えませんでしたが、DMMが複数の事業ユニットを閉鎖する要因となりました。

    .jp/Pawoo について:

    私たちの他事業においては、DMM との提携が一層強化されています。前CEOのTarbrick氏の退任と創業者の亀山氏の復帰を経て、最終的には同社の子会社の株主にもなりました。この枠組みには、Square Enix、Netmarble、そしてBitfinex(Tether)といった大手企業も関わっています。

    こうした背景から、日本のゲームおよびクリエイター産業において大きな影響力を持つDMMとともに、Pawoo/.jpを次のステージへ進めていきたいと考えています。
    詳細はこちら:
    https://dmm-corp.com/press/service/3373/

    この当初の計画が順調に進めば、Fediverse全体にも大きなメリットがもたらされるはずです。

    先週以降、このOAuthに関する問題はMastodon公式バージョンで修正され、これらのサーバーをスムーズに最新バージョンへアップグレードできるようになりました。

    .cloudの今後について:
    日本の法律では一定のポルノコンテンツが明確に許容されており、私たちのチームもローカルコンプライアンスには対応可能です。一方で、欧州の規制に関する知識は限定的です。そのため、.cloudについては、より適切に対応できる現地パートナーへ移管する可能性があります。その場合、私たちは自社エコシステムとの互換性を維持するため、DID/認証関連の一部のみを引き続き担当する形を想定しています。

    Pixiv のOAuthを利用するためには、Mastodon 公式(Mastodon Org)のバージョンをフォークし、独自機能を追加する必要がありました。その結果、これらのサーバーは最新バージョンへのアップグレードが難しくなっています。

    当時、Mastodonチームも人手が非常に限られていたため、私たちは資金面だけでなくエンジニアリング面でも支援を行いました(例:iOS版Mastodonアプリのコードベースの提供など)。詳細はこちら:
    https://blog.joinmastodon.org/2023/11/thank-you-sujitech/

    また、MastodonチームがEUおよび米国で2つの非営利団体を設立したことを大変うれしく思っています。私たちもわずかながら貢献し、他の重要なドナーの紹介にも関わりました。

    2022年には、pixiv 内でのつながり(ディレクターの清水氏、デザイナーのGoding氏、そして後に DMM のCEOとなった創業者Tarbrik氏)を通じて、Pawoo をRusselから引き継ぎました(Russelはpixivと関係が深く、Pawoo自体もpixivによって立ち上げられたものです)。

    これにより、日本と欧米、特にEUにおけるポルノコンテンツ規制に対する姿勢の大きな違いという、私たちにとって特有の課題が生まれました。

    Pawooの独自のカルチャーを維持するため、私たちはpixivとの間で、同社のOAuthを引き続き利用するための契約を締結しました。→

    私たちは2020年6月(6年前)に、日本のチームから Mastodon のインスタンスである mastodon.cloud と mstdn.jp のメンテナンスを引き継ぎました。これらの資産は米国の会社の下に置かれ、その後、日本の関連会社を含む体制へと整理されています。

    それ以降、運営は完全に非営利の形で行っており、短期的なビジネス利益は追求していません。

    しかし、チームの誰もヨーロッパに拠点を置いておらず、また日本とEUの規制の分断がその後さまざまな問題を引き起こしています(詳細は次の投稿で説明します)。

    While in the states, Meta’s threads seems to be helpful to Fediverse (with 0 donations and grant to mastodon or any open source org haha…); we remain confident that we will help find very strong and reliable partners in Asia for Fediverse. It’s sad that decentralized social did not have a chance to partner with DMM due to unfortunate circumstances; but we already know it’s very possible and likely few meetings away.

    Here’s my part of stories and thoughts for helping mastodon. Thanks for reading

    These events lead DMM to close several business units and unable to move forward into decentralized technology including decentralized social that much. DMM have been extremely responsible by compensation all affected clients and returning money to all related shareholders. Mr. Kamiyama keeps clients and business liabilities as priority and he’s a man of his words.

    Just like how big impact Pixiv bring to Fediverse; We were hoping DMM can be way more impactful and also friendly (compare to Meta’s thread);

    However, in 2024 Jun, DMM got hacked 48.2B JPY (300M$) by North Korean state backed hackers. Few months later in 2025 I’ve personally hacked for 4M$.

    Luckily these events did not impact me that much; however it did lead DMM to close multiple units.

    On .jp / Pawoo:

    Our other business have strengthened partnerships with DMM, after their prev CEO Tarbrick left & founder Kamiyama returned; and eventually become shareholder of their sub company, with other big companies such as Square Enix, Net Marble and Bitfinex (Tether); naturally, we also want to bring Pawoo/ .jp into next stage given how big DMM is in Japanese game & creator industry.
    More info: https://dmm-corp.com/press/service/3373/

    If this original plan goes well, the whole Fediverse will benefit.

    Since last week, the OAuth problem have been patched by Mastodon’s official ver and we can smoothly upgrade these servers.

    For the future of .cloud:
    Given Jp law explicitly allow certain porn; our team is trained with local compliance capabilities; however with little knowledge of European compliance etc. We might transfer out .cloud to a local partner who can do it better; while we only keep maintaining certain DID/Auth parts for compatibility with our other ecosystem apps.

    The OAuth of Pixiv requires us to fork and add different features on Mastodon Org’s versions; which makes these server hard to upgrade to latest versions.

    At that time Mastodon team is also very man power limited, so we’ve donated both financially and engineering effort (such as the code base of iOS ver mastodon app). More info: https://blog.joinmastodon.org/2023/11/thank-you-sujitech/

    I’m super glad that mastodon team have established two non profit in EU and US; and helped contributed a bit and introduced other key donors.

The operations team is currently evaluating the feasibility of a server version update. Please follow @TheAdmin for future updates on progress. This is actively being worked on now with @MastodonEngineering team.

    In 2022, through our connection within Pixiv (their director 清水, their designer Goding, and founder Tarbrik who then became CEO of DMM) we also acquired Pawoo from Russel (who is close to Pixiv and Pawoo was founded by Pixiv). This created a unique problem for us, the completely different attitude of porn content regulation of Japan and other western countries, especially EU.

    In order to maintain Pawoo’s unique culture, we’ve entered agreement with Pixiv for keep using their OAuth —>

    On mastodon.cloud :

    We took over the maintenance of Mastodon.cloud together with mstdn.jp from a Japanese team in 2020 Jun (6 years ago) and sit these assets in a U.S. company and later Japanese sister companies structure. Since then, the operations are purely in non profit manner and we are not looking for short term business.

    However, non of team are based in Europe and later the split between regulatory between Jp and Eu causes more problems (I will explain in next toot)

    @warning @Linux @Sujiyan @mellifluousbox @haubles The instance maintainer is active and engaged, regularly posting content. The instance is funded, and the organization behind it has a track record of supporting and developing Mastodon.

    The conflict: (1) .cloud is based in Japan, (2) they aim to keep the instance open, (3) they lack dedicated admin and moderation teams, though that’s common across many instances, and (4) it’s one of several internet projects they support, not a primary focus.
