Check-ins]] ### Explanation When two or more accounts check in at the same venue at the same time — a bar, a restaurant, a concert, a gym — that's strong evidence the people behind those accounts were physically together. Check-in-driven apps (Foursquare/Swarm, Untappd, fitness platforms) make these timestamps and locations public by default, and the same effect appears in tagged photos on Instagram and Facebook places. Pull the check-in history of the primary target and look for venues with low background traffic — a chain coffee shop is noise, a small private club is a strong signal. For each such venue, list the other accounts that checked in within a few minutes either side. Repeat across several sessions and the recurring co-presence pattern surfaces close friends, partners, and colleagues who otherwise have no public link to the target. ### Examples {{some links to articles, videos, etc}} ### Tools [untappdScraper](https://github.com/WebBreacher/untappdScraper#untappdscraper) ### See also - [[SOTL-3.1.
