U.K. watchdog group Privacy International has sparked an inquiry into eBay's handling of personal data, as part of a new campaign against e-commerce sites that may be abusing the privacy of their users. The civil- and cyber-rights group complained to the U.K.'s Information Commissioner about eBay.co.uk, which it claims is breaching the Data Protection Act by making it hard for users to cancel their accounts and delete details of their Web shopping habits and other personal data.
