Oh. Maybe I’m onto something here. It’s Kut so it has to do something with racism, so I googled “white nationalist 13” and the first hit was from the ADL. Some group that calls themselves arian circle and one of the symbols they use is 13. So first and third letters mean AC.
I don’t ever recall INGO talking about them. But I don’t read every post of every thread.
Kut, if that’s it, that 13 clue is really out there.
The ADL legitimately has every possible number combination marked down as something racist, so I highly doubt that's it.
