The history quiz or songs quiz by QuizGriz featured on this site and others is actually a phishing scheme to obtain control of your email account. Once you complete 100 questions, you are required to submit your email to obtain the results of your test. The submission of your email also requires the sucker to reveal their email password. This enables the perpetrator to control the tester’s email and use it for whatever purpose they desire. It can be used to send disinformation to anyone on the naive user’s email list or to any person or group in the name of the owner’s owner.
