First NANOG post, the topic compels me to chime in.
For me, the question also implies that user-side we are attempting to scrub any of the data we volunteer on social media (or other) platforms. I am careful about what I volunteer up to the Internetz, and have been since my first AOL floppy experience.... So, the question of do the ISPs collect data is particularly important because regardless of how careful I am to anonymize my own contribution to my "online profile," Tom's assessment is the bleakest possible picture for anyone attempting to limit the data set which represents us.
