The NSA manages something on the order of dozens of Zetabytes of information. I am not particularly worried about them linking my IP address to "FartSnifferFanatic.toot"
However, I am very concerned with FartSnifferFanatic.toot littering my browser history and cookies cache with trackers that Amazon can then use to suggest purchase ideas.
I have this fantasy where the NSA gets hacked and everybody's porn preferences get leaked at once. Since it's everyone, society just accepts it, the stigmas fade, and America becomes just a little bit less puritanical.
I'm sure the NSA has been hacked multiple times in its history and I am just as sure you will never see a news report to that effect published anywhere in the United States.
