A single post addressed to the X account, which the researcher says keeps changing names, listing two GitHub accounts and three Gmail addresses under it; the addresses are written as local parts in the post and completed here with the domain the post names. Two of the addresses carry the names Oliver Boucher and Henry Campbell, which the post does not otherwise state, so neither is recorded as an alias. Three screenshots accompany the post.

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/svendotdev is account id 128123195, created on 17 March 2023, with 101 public repositories. Its noreply addresses name the handles secretariatv and tera-star, so it is the account KawaiiJongUwUn names as github.com/secretariatv under rarosem, renamed; secretariatv now returns not found. Its repositories hold 100 commits signed oliver.boucher.25@gmail.com, 67 signed oliver.b25.f@gmail.com and 3 signed henry.campbell.1225@gmail.com, all addresses the same researcher gives for rarosem. Seven of its own commits are signed mikestar.db327@gmail.com.
