I'm not sure how recent those articles were added, but at least as of a year ago when I tried to post something on ProductHunt, part of the post creation flow (which is quite intricate and a story for another day) explicitly encouraged you to post on social media and "share" with friends. Almost every PH post these days has a little back and forth comment thread between the maker and the people who they've clearly asked to upvote and/or comment.
