As users of technology we need to take responsibility in helping secure our personal data, because if we don’t those assets could be accessed without our knowledge/permission and even worse our identity could be stolen.
Information beyond name and email such as birthdate and address should not be provided freely as a best practice – you should only provide this information to trusted companies with which you have an established relationship. Surveys should not need that level of personal data. And if you are asked for that level of personal data via a survey, you should be extremely cautious.
