Isn't this already standard practice? (Score 2, Informative)

Every ISP I have ever worked with has kept logs of assigned IP for dialup, caller id (when available and not cost prohibitive), email and ftp server logs. These logs are referred to when following up complaints of abuse (mainly spammers). Even if an ISP were not interested in fielding abuse complaints, they would be insane not to keep this information in the face of subpeonas and requests for cooperation by law enforcement (and lately DMCA notices).

Why is this a violation of privacy? While the information may be handled casually in many cases, it is not published publicly. Do users really think they have an expectation of privacy in this way? Do they really think they have a right to be untracable and unaccountable for their actions online?

I know slashdotters seem to be always fighting a losing battle for privacy, but these logs seem to be common sense.
