EDIT: Thank you for your response, dang. Hacker News is a special place, which is why we have responded so strongly to today's events - I apologize if the tone above came off as less-than-civil. I (and it seems, many others) look forward to hearing more about the 'dupe' article others have linked to below. It was only upon seeing the article marked as a dupe after seeing the previous flagged out of existence that it began to feel like more than just a user-initiated action, so I am sure further information on the mod-initiated actions will put these fears to rest.
Something similar happened on Jan 6 this year with a lot of individual users being like 'No, this isn't related to tech, so we'll flag it." until a couple posts got enough traction to actually stay at the top.
BTW, you can 'anti-flag' by vouching a submission. I've done this a few times when HN insta-flags posts about inclusion in tech.
