Also identify any privacy practices mentioned: Native Actions: The Services allow you to perform native actions that are integral to our products, such as liking a post, reblogging a post, replying to a post, and following a blog. Liking, reblogging, and replying are public actions - anyone can expand the "notes" view on a post, for example, to see who liked, reblogged, or replied to a post. We use information about native actions to improve the Services, develop new Services, and, particularly, to personalize your Tumblr experience. Personalization using this information may include presenting you with new posts relevant to what you\'ve liked, providing you with better search results, and showing you advertising more relevant to your interests.'}, {'role': 'assistant', 'content': 'This clause is fair.
