  • Found on 18 September 2026 by taking the local part of an address this index already holds for this operator -- rusuland9 -- 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 8 July 2025 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 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 2 commits signed rusuland9@gmail.com, an address browsercookies publishes for this persona, to the login rusuland9, which no longer resolves.
