  • Found on 24 September 2026 by searching GitHub's commit index for every personal address this index transcribes from researchers' posts, and keeping the accounts whose own commits are signed with one. GitHub mints a noreply address from an account's immutable numeric id, in the form id+handle@users.noreply.github.com, so the former handles below are a matter of record. Counts of an account's own commits are over the 100 that GitHub's search returns for it. github.com/marksantiago290 is account id 133281370, created on 11 May 2023, with 100 public repositories. Its noreply addresses name the handles marksantiago02, marksantiago2909, btc415 and its current one, so it is the account browsercookies names as github.com/marksantiago02 under Mark Santiago, renamed; marksantiago02 now returns not found. Its repositories hold 70 commits signed marksantiago0929@gmail.com and 66 signed alenschmitt415@gmail.com, and 42 signed stevenpiao0822@gmail.com, which the same researcher gives for Steven Leal.

From gh-fake-analyzer 1.0.2, the Ketman Project's GitHub analysis tool, run on 2026-10-06. 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.
