The number of submissions per hour keeps growing and so is the number of spam, off-topic or previously banned user accounts. I currently see 12 of the last 30 submissions are marked [dead] with one flagged, the others were auto-blocked by algorithms. (I have no knowledge about the algorithms other than observing as an outsider). More users are needed to go through the
https://news.ycombinator.com/newest list and click 'vouch' on interesting submissions. I regularly do but even just reading every headline is time consuming.
