Rarely. I can count the number of times I've red repped on one hand. Only once have I red repped for disagreeing with a post. Someone said Taylor Wilde sucks, so I red repped them. The others all came from instances when the person really upset me. My Verbal RKO to Monkey a few months back did NOT come with a red rep, if that tells you anything. I only do when I think someone truly deserves it. Red reps from me are rare as hell.
