Not sure how I improved my comment reputation exactly. I couldn't get points for upvoting, or commenting, nor making memes. But I could get points for upvoting/downvoting memes. Once I hit 10 points I was out. Huh. Not sure what triggered it. Might've been this meme... or I got flagged for the circle jerk. I doubt getting downvote into oblivion triggered it but it's not impossible.
