It's traffic analysis. They know when something 'subversive' gets posted, they can filter out who was connecting to the site at that time, get a list of suspects. Obviously 99% of the traffic is coming from mobiles which have great metadata tagging already, also geolocation. Cafe wifi you can use from across the road, in a busy place etc, much harder. |
