Two ways to catch a pattern

That should have been the end of it. What made it not the end of it was that Dare posted about it in the group — annoyed, wanting sympathy — and a woman in Ikorodu said wait, and put up a screenshot of her own from three weeks earlier, and the client's opening message was the same. Not similar. The same, word for word, including a comma in a strange place.

By the following evening there were nine of them.

Nine workers, four months, four different client accounts, one paragraph of text. Every dispute filed two days after a verified completion. Every one of them dead on arrival, because the code was in the frame and the machine had seen what it saw and would not be argued out of it.

"Dem dey test," Chika said, in a voice note at midnight that the group played about four thousand times. "Nine time. Dem dey knock the door to see wetin dey behind am."

What she did next was the thing that mattered, and it was not sophisticated: she posted the four client account handles in the group, and one hundred and forty people declined to work for them, and the accounts went quiet inside a week.

The Alájọ̀ had already flagged them internally by then — four accounts, disputing at eleven times baseline, every dispute against a verified unit, was not a subtle pattern. The standing of all four had degraded automatically with each filing, which is exactly what it was designed to do.

But the machine had caught it in aggregate, after the fact, statistically. The group had caught it in particulars, in an evening, because a woman in Ikorodu recognised a comma.

That was the discovery of the autumn, and Chika said it out loud in the group and then said it again to Adaeze, who wrote it down — and who sent it that night to one person in Cuenca, Ecuador, who replied at four in the morning with two paragraphs and a question, and neither of them did anything with it at all, which was mostly what they did. The ledger is the memory, but the market is the witness, and the market is faster. The machine remembered everything and noticed slowly. One hundred and forty people remembered almost nothing and noticed in a night. Neither worked alone.
