The upside-down question mark test

A comment appears under yesterday’s CV video, articulate, on-topic, complimentary: “me encantó cómo detallaste la importancia de incluir métricas concretas en la hoja de vida” ▸ 34:55. Username: @linapbot. The teardown that follows is a small field guide to unmasking machines, mid-2025 edition.

The prompt injection as Voight-Kampff test.

Then the entry eats its own tail, twice. Juan notes the window is closing: nothing stops a bot from being trained to write “como uno”, slang, LOL, even a family-group-chat aunt’s spelling mistakes, at which point every tell above dies ▸ 39:05. And he catches the irony live: it feels “bizarro” to give your time to something that doesn’t exist, “chistoso que digo eso y me la paso todo el día con Cline” ▸ 38:22.

Filed as dated evidence: the first bot fan arrived on day 268, and it was polite…
