maybe a video tape? kinda like SAW?
Perhaps. It can be discussed. What does he value more, his testicles or his two hands. Then you could put a trap on both and tell him the key is hidden behind his eyesocket for his testicles, so therefore he loses his hands anyways. I don't know, something of the sort.
But the matter remains, mentlegen. Sortie and take down the spammer.
