So yeah, when mole hunters catch a mole (and I'm talking about the little blind mammals here, not CIA plants) they string them up on the nearest fence as a deterent to other moles. Possibly. Or maybe its so that the seagulls and crows can eat the bodies. But then you'd just be substituting one pest for another which'd be stupid.
Anyway, what I was trying to say was, when people make things like "Hi, I'm new" threads, lock it and sticky it -- not all of them obviously, just a few to act as deterents to other new people.
If nothing else, it'd let the mods bask in their glorious kills like heads skewered to pikes on London Bridge.
