While it's not exactly a novel technique (I've read similar stories since the early 2010s at least), I'm continuously surprises by how much people are able to glean from inferences and online sources. The saga of the "he will not divide us" flag is particularly impressive.

It's called OSINT and it's been around a lot longer than 2010.

I'm not sure why 'def8cefe' is being voted down for pointing out the name of this process. OSINT is short for "open source intelligence" and the TL;DR is that only "open sources" (eg: not government/restricted datasets) are use to perform a digital investigation. Steve Rambam has given talks about digital investigations from the very beginning of the H.O.P.E. Conferences on this topic. In addition to law enforcement using this it's also used by private investigators or just amateur enthusiasts who team up to help solve missing children cases and track down info from other past cold cases or to even bust child trafficking rings. The skills natural to Hacker News readers makes me surprised there's not more general interest in OSINT here, especially defensive tactics to make sure we allow as little of our personal info to land in open datasets to feed OSINT investigations in the future.

There is interest in OSINT but my comment could be misconstrued as supportive of or normalizing LE practises so that upsets a very vocal interest group on the Internet.
