You might recall that before snoopvertising agency NebuAD flamed out spectacularly, a number of ISPs tested the user-tracking technology on their customers -- in many cases without telling anybody about it. When asked by the press about the tests, many of these ISPs simply wouldn't comment. Ultimately WOW, Charter, Embarq and all of NebuAD's clients faced a public relations disaster when their quiet tracking of your online behavior became public, so they suspended their efforts. But now each of those carriers is facing legal action, with Cable ONE being the latest according to Courtroom News:Of course many of these ISPs made things worse for themselves by simply not being transparent with their users. Carriers were so excited by the possibility of a new revenue stream (rumored to be around $5 per user, per month), that many were willing to bypass all privacy and consumer concerns. Several ISPs made things even worse by lying before Congress in August of 2008 about the depth of their information sharing and the usefulness of their opt-out systems. While many ISPs didn't even bother with opt-out systems, other ISPs implemented cookie-based opt-out systems that simply didn't work.
