This is huge privacy concern for you the consumer, this cannot be blocked because the ISP know every move you make.Charter to Snoop on Broadband Customers' Web Histories for Ad Networks
.........Charter is partnering with a company called NebuAD to build profiles of its users. NebuAD will share the behavioral tracking results with third-party advertising networks like DoubleClick. Users can opt out of the system, but have to give their full name and address to get an opt-out cookie. The process would have to be repeated for every browser on every computer in a home to block the service, and would have to be reset if cookies are ever deleted.
Charter is entering tricky territory with the program, which effectively turns the ISP into the ultimate third-party tracking network. Conventional ad delivery networks like DoubleClick use a third-party cookie to build profiles of users across different websites, but can only track visits to sites that serve the company's ads. In contrast, Charter will know every URL its customers visit.
It's also a concern for me, the technology by Nebuad can also be used to insert ads into web pages. For example you come here and there's a additional ad on the side of the page. I've said it before and I'll say it again, any ISP that attempts to place ads on my pages will be blocked, they aren't doing it yet but in the event they do begin to do that I have every intentions of following through with that plan. I'll also add I won't be alone as many webmasters have the same intentions as me.
