It's not really something I can teach.
There's a certain subtlety involved, of writing style and organization of facts. I can't generally use my bullshit detector, as it usually applies to the 'genuine' programmed parents and staff, who lie constantly. But there is a certain word order and phrasing done when someone is writing fiction instead of fact. Some things said, some things not said. And of course (as in this case) there's a few extremes done, just pushing it to the limit to see how dumb the programmies are.
Of course "how dumb the programmies are" is like "how wet the ocean is". The programmies never can tell the difference and so they can be trolled indefinitely. If I could stomach ST I'd construct a whole new social reality for them, and then start having my trolls being mysteriously killed one by one...
