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 18 September 2026 by taking the local part of an address this index already holds for this operator -- blackhorse0215 -- and asking GitLab whether an account exists under it. The address is on a consumer mail host, where the local part is a login the holder chose rather than one an employer assigned; handles taken from company addresses were excluded from this pass for that reason. The account states a display name of Black Horse. The display name is kept here rather than carried as an alias, because it restates the handle, describes the work, or is too bare to be a name. The login is what links this account to the rest; nothing here establishes that one person holds both, and a display name on a profile is a name the account presents, not an identification.

Found on 18 September 2026 by taking the local part of an address this index already holds for this operator -- dreamfullstacker -- and asking dev.to whether an account exists under it. The address is on a consumer mail host, where the local part is a login the holder chose rather than one an employer assigned; handles taken from company addresses were excluded from this pass for that reason. The account states a registration date of 29 May 2022 and no display name but the handle itself. The login is what links this account to the rest; nothing here establishes that one person holds both, and a display name on a profile is a name the account presents, not an identification.

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.

Found on 24 September 2026 by searching GitHub's commit index for published persona addresses and reading which account GitHub attributes the commits to. GitHub credits a commit to the account that has the signing address registered and verified, which only the holder of the mailbox can do, so an attributed account is one the address's holder controls, whichever repository the commits sit in and whenever the address was added. Counts are of the commits GitHub's search returns, up to 100. GitHub attributes 74 commits signed smallstar0924@gmail.com, an address browsercookies publishes for this persona, to the login Caesar0dev, which no longer resolves.
