In "real" life a can normally spot a wind-up a mile off. But on here it's very difficult if not impossible. It gets so bad sometimes with Scunner, Crabbit and Tink that I decide that they are at it all the time. Then of course, when they are being serious, I end up putting my foot in it.
Anyway, have you suffered from a really good wind-up and/or are you a wind-up merchant yourself and which is your favourite.
