Above is a screenshot of one of the comments in my spam filter (click to embiggen). Sometimes real comments get lodged there, so I check periodically to make sure nothing needs rescuing, and initially, that seemed to be what had happened here. Citing Wayne Booth is usually pretty convincing evidence that you’re a real person.
A second look, though, draws attention to the link that redirects to some sort shady online “nutrition supplement” operation. Clearly, the spambot culled a few sentences about unreliable narrators from Google Books or an academic website. Still, the precision of that targeting is a bit eerie. If the spambots read enough narrative theory, will they become self-aware?
