A Comcast ISP subscriber sued his ISP He lost. The result is that customers should have no expectation of privacy from their ISP. They can and will store everything you do online.

Plaintiff Jeffrey Klimas said that Comcast violated the Cable Act by storing personally identifiable information without the knowledge or consent of its subscribers. What is disturbing is that the data wasn't just IP addresses, but visited web sites and data sent to them, file downloads, and email.

Cable operators are only legally allowed to collect data that is necessary for providing cable service. Such rights don't extend to storing that information.

The U.S. District Court for the Eastern District of Michigan and 6th Circuit of Appeals ruled against Klimas on different technical grounds. District Court said IP addresses are not personally identifiable information as defined by Cable Act law. Circuit Court said the Cable Act protects only cable customers, not ISP customers.
