I think about this too. It's got a conflict ("he's doing something I don't want him to do"), it's weird enough to be eye catching but not weird enough to be unbelievable, serious enough to warrant concern but not so serious that it isn't funny to read and think about, and comes with an explicit invitation to engage. It's got relatable themes (loneliness, male hobby obsession, finding fulfillment outside the drudgery of work) and has an easy entrypoint for engagement.

I'm not saying this is fake, especially since it wouldn't really matter either way, but it's interesting to think about. I remember reading something about people who fake advice column letters. There's a real art to the best ones.
