Someone is Printing out Missed Connections and Posting Them on the Street
The Craigslist Missed Connections sub-category, an endless form of entertainment, is now the subject of an apparent street campaign. Someone is printing out the online posts and distributing flyers of same.
The links included at the bottom of each of the handbills forwards to the relevant Craigslist post. Most have since expired.
Or this is probably just another elaborate marketing stunt to promote a dating app or sell contraceptives, or some such.
