Shouldnt the mods be able to reveal who's smiting whom?
Mods don't have that info. If you wanna get anal about it and someone is smiting you, you can camp out on the Who's Online page hitting the F5 key and simultaneously watching your karma count.
Other games that have been done (most of them require admin status:)
~ get an admin to max out your negs (it's somewhere north of 55K, or used to be)
~ turn off the karma clock and have a karma war
~ write an app that will smite your enemy as often as the clock allows, even while you're sleeping
~ disable the karma function altogether
~ etc etc.
