Deletion is a canard
the funny thing about user data deletion is that even the data companies have identified and catalogued isn't deleted :) it's still technically infeasible to delete data from most data warehouses
How does advertisement surveillance work?
I still don't understand the attack-vector how buying targeted advertisements can be used to unmask particular individuals (the example in mudge's testimony: democracy-desiring Chinese citizens posting on twitter illegally).
can anyone explain this to me?
if the users are accessing twitter + any ad clicks through a GFW-bypassing VPN, and china can target an advertisement to a single user, then they can figure out that that user uses a VPN if they click on the advertisement? how do they unmask the VPN IP address? my understanding is that VPN providers (should! i hope!) internally transit the traffic so that the exit node isn't the same as the IP address the GFW would see users connect to, so i'm not sure how they could correlate that traffic to a "real" IP/identity.
