Found on 24 September 2026 by searching GitHub's commit index for the addresses researchers give for this persona, and for the addresses of the accounts already filed under it. Counts of an account's own commits are over the 100 that GitHub's search returns for it. github.com/engineer10223 is account id 248745798, created on 9 December 2025, with one public repository. All 100 of the commits GitHub's search returns for it are signed okawamasaaki916@gmail.com, an address browsercookies gives for John Benrey Diohen Filio. Because GitHub attributes a commit to whichever account has the address registered, this account now also owns the persona's 2024 commits in github.com/frostyalce000's profile repository, made more than a year before it was created: the address was registered to it afterwards.

From gh-fake-analyzer 1.0.2, the Ketman Project's GitHub analysis tool, run on 2026-10-02. These are signals: backdated history and several commit identities are common among ordinary developers too, and an account that shows none of them is not thereby cleared.
