I agree. I "revived" the comment by clicking on the timestamp ("33 minutes ago") and then clicking "vouch". I believe only users with a score of 200+ (points? karma?) can do so.
replyBeen here 8 years, always wondered how comments died. I assumed it was algorithmic. TIL
reply“[dead]” usually means algorithmic (could be as simple as an account registered via Tor that hasn’t been vouched for enough times). “[flagged][dead]” usually means it was flag-killed by users, except I’ve been noticing some AI written comments that are flagged instead of just dead, but they’re minutes old so unlikely to be user flagged.
replyThere's been an "AI comment detect" algo trialed and running for a month or so now.
replyIf you see any probably human comments tagged as Mr Roboto either vouch (weak indication, needs a few others to boost) or email hn@<this site> for dang / tom to cast a meat based eyeball over it.
I wondered that too. It doesn't say, but does state: "Data from the license plate readers, known in law enforcement as LPRs, was searched 62,000 times in 2025, leading to about 1,660 cleared catalytic converter theft cases, a report from the authority said."
replyAlso, how many missing people are there? finding 10k seems quite a lot. “one of the most effective ways Flock has been able to help find, just last year, over 10,000 missing persons”.
The term "missing person" calls to mind someone who is in serious danger, but a majority are something minor, like someone quitting a job without notice or taking an unannounced trip. The vast majority are resolved by finding the person alive.
replyFlock helping close 10K cases doesn't surprise me at all, but it doesn't meant those people wouldn't have been found without it. It may mean less work for the police, but the police don't usually put a lot of effort into a missing person without evidence they're in danger.
Based on the cited document, "leading to" seems entirely made up.
