A Washington-based privacy group filed a complaint Feb. 10 before the Federal Trade Commission, alleging that DoubleClick Inc. has engaged “in unfair and deceptive trade practices by tracking the online activities of Internet users and combining that tracking data with detailed personally-identifiable information contained in a massive, national marketing database.”

The complaint by the Electronic Privacy Information Center (EPIC) came two days after the FTC notified the company that it was engaged in a “routine inquiry” of the company’s privacy policies. The complaint, which comes on the heels of a recent private lawsuit against DoubleClick that makes similar allegations, seeks similar remedies.
