In all honesty, -400 or -500 karma is quite ridiculous indeed. I won't judge whether it's deserved to be that low or not, but as Abnaxus said, give a break to the guys! You don't need to like them, you can even keep clicking 'smite' daily if that soothes ya, but keep the irony and provoking for yourself if you're not provoked. It's what grown up and selfconfident people do.
@Crash: your karma stays, as it seems. Don't you think there are ways to improve it a bit?
