You just failed a test of your ability to avoid a phishing attack. You clicked an invalid link and you could have been attacked. Please ONLY click on links that you are 100% sure are valid links sent by valid email accounts. If you aren't 100% sure, validate with the email sender that he or she sent the email to you and that it is safe. Check the sender's email address BEFORE clicking.
