Maybe a dumb question, but how can you brigade against on Hacker News if there is no downvote of submissions?
But maybe even some light flagging, plus high engagement-to-view ratio (esp. if engagements go many levels deep fast), may cause some "unwanted" content to be buried.
And just to clarify, if enough people flag submissions,
but not enough people, then it can get buried but not get
the "flagged" tag?
As far as I'm concerned it's either that, or explicit moderation action to downweight links to DF and other selected domains.
