[{'role': 'user', 'content': 'Analyze the following clause from a privacy policy and determine if it\'s fair or unfair. Also identify any privacy practices mentioned: In connection with certain activities or services, we may collect a child\'s online contact information, such as an email address which is collected from the parent, in order to communicate with the child more than once. In such instances we will retain the child\'s online contact information to honour the request and for no other purpose such as marketing. One example would be a newsletter that provides occasional updates about a site, game/activity, television show, personality/character, or feature movie. Whenever we collect a child\'s online contact information for ongoing communications, we will simultaneously require a parent email address in order to notify the parent about the collection and use of the child\'s information, as well as to provide the parent an opportunity to prevent further contact with the child. On some occasions a child may be engaged in more than one ongoing communication, and a parent may be required to "opt-out" of each communication individually. Parent\'s may opt their child out from receving these types of communications by following the unsubscribe instructions located within each communication or by emailing us at http://service.lego.com/contactus.'}, {'role': 'assistant', 'content': 'This clause is unfair.
