Your comment was previously near the top because newer comments always start near the top. It's gone down because it has failed to attract enough upvotes and newer comments have taken its place. It doesn't take a moderator shadowban for a negative comment to lose ground on HN.

I know how HN works, but thanks for explaining it. New comments are only given the top spot for a small time period. My comment was at the top long after said time period, because it previously had more than enough upvotes to stay at the top (in fact, it actually had been knocked down to middle-ish of the thread, and then garnered enough upvotes to again be the top). As soon as dang commented, it suddenly was at the bottom.
