Regardless of why the author thinks they're sad, it's a mistake to project the mental and emotional state of someone based on some facets gleaned from checking out their social media profiles. It's actually kind of creepy to focus on this individual especially since they're a teenager and aren't given a chance to rebut.

I don't see much psychoanalysis involved. I see a description of someone with dubious goals who is getting played by bots into believing they're making progress.
