A couple of questions, as I worry that "flagging" can be abused by small groups of motivated people who are not representative of the broader user base.
Do you have ways to prevent "flagging abuse"? e.g. Do you review why things were flagged, and reinstate them if for example the thread has a lot of upvotes and isn't a total flamewar, or if the flaggers weren't particularly good citizens?
Most stories and threads that get enough flags to win the tug-of-war against upvotes are just not very good or on topic for HN. Partisans of one side or the other on an issue tend to feel strongly about it, but the bulk of the audience is here for interesting things to read, and the site has a very clear mandate that way: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor..., https://news.ycombinator.com/newsguidelines.html. So most of the time, when people feel strongly that a story shouldn't be flagged, we end up disappointing them; fighting these battles is not really what HN is for. Still, there are fairly frequent exceptions.
I should add that when an account has a habit of flagging submissions that are on-topic and good submissions for HN, we eventually take away their flagging privileges.
I'm sure most of us would agree that the quality of the moderation here is the reason this site has been so great for so long - thanks again for all your efforts.
