The 60 or so companies listed by the Center for Democracy & Technology Web site as users of DoubleClick's network were each flooded last week with more than 4,000 messages in two days from consumers expressing concern about privacy issues relating to DoubleClick's plan to combine online tracking and offline profiles. Ari Schwartz, a policy analyst for the group, said the center's ability to e-mail was temporarily cut off Thursday after some of the companies complained to its service provider. Some of the companies, in letters on the group's Web site (www.cdt.org), denied letting DoubleClick do anything other than serve ads. Mr. Schwartz said more than 8,000 messages have been sent to DoubleClick.
