I'm personally not very well-known, but I work for someone who is, and on a project that gets quite a lot of attention because of it. It's surprisingly common that people show up with extraordinary and incoherent stories. Given the author's name and email address are plastered all over, it is not surprising that such people would find him too.

An article was shared here a while ago that went into that as well: https://tim.blog/2020/02/02/reasons-to-not-become-famous/
