It also said that it would vigorously defend itself in this matter.Amazon spokeswoman said that they strongly disagreed with the CNPDs ruling and would appeal. The decision regarding how customers see relevant advertising depends on subjective and untested interpretations under European privacy law. The proposed fine is completely out of proportion.The data protection authority also requests "practice revisions," which cannot be described in the document.The fine is now higher than reported previously.
