It's true, there could definitely have been confounding factors and I wish there was a better record than their memories. I remain personally convinced due to knowing and trusting the involved parties, but agree that the anecdote doesn't (and shouldn't) carry much weight as objective evidence. This seems like something which privacy researchers might be interested in, and wouldn't be too difficult to run - I wonder if anyone here can point us towards any more formal experiments that have been run on this? Edit: The more I reflect, the more difficult the experiment seems to be. How does one recruit for an experiment, contact and instruct participants, etc., probably via surveilled email or messaging platforms, without creating data linking participants to one another?
