Please don't. In HN threads the main thing to optimize for is signal/noise ratio, because that is what serves the site goal of intellectual curiosity. This is why the site guidelines ask you not to go on about getting downvoted: https://news.ycombinator.com/newsguidelines.html.
Downvotes are irritating, of course, but it's an irritant we all have to deal with.
People who complain about downvotes get downvoted, especially if they make a whole new comment (or more, wow) just to complain.
