These aren't local credentials, these are credentials from various third-party websites that made their way into stealer logs. Garbled or not, using your personal email address for both legitimate purposes (e.g. Google Calendar, as the article points out) and honeypots isn't the best idea.

Ah, I thought you meant what sites list the stolen credentials. The exact overlap of websites across four separate stealer logs is enough to leak an email address pretty reliably. The only thing that's "telling" for is that they're not willing to dox this person.
