That would be awesome to send a message that said "I'm way too fuckin awesome for karma. Take that shit off." The mod then replaces you karma with a little sign that says "I don't give a shit what you think so I took the ability for you to tell me away."
what it really means is "my karma should be higher than it is so instead of wanting it to go higher i'm just gonna ask for none"just don't pay attention to it, i stopped a while ago
