When Phil Ford says "blackjacked" does he mean it in the sense of being cudgeled or does he mean it in the sense of being blackmailed? Or is it something else entirely?

I've created an online trilateration calculator using Desmos 3D, which I only just learned about. I've always loved Desmos, and in the past, I've had to do some pretty silly workarounds to get things to work in 3D on there, but it turns out they released a 3D mode about two and a half years ago. https://axelstewart.neocities.org/other/trilateration
