The four posts are one thread by the same researcher. He names the operator Janus or Angel in the second, calls him Star boy in the third where the addresses are described as the older ones, and adds the last address in the fourth alongside a remark about a GitHub account holding sixty repositories, which the post does not name.

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/webmobileai is account id 108163680, created on 25 June 2022, display name WMAG, with 111 public repositories. Its noreply addresses show it was previously named seniorsoftdeveloper. 91 of its own 100 commits are signed softdeveng9211@outlook.com, and its repositories hold 66 more signed fullstackdev3546@gmail.com; browsercookies gives both for the operator the researcher calls Janus.
