New Online Scam

Lately I have been getting a lot of offers to receive a free gift card if I would just fill out a survey. I counted fourteen of these emails in the past two days. However, if you look carefully they all say "Participation Required." After you take the survey, you find out that you have to purchase a certain number of gold and silver offers before you become eligible to receive the gift card. The email addresses are also suspect. Why would an offer for a Kohl's giftcard come from the email address info@captainbivalve.com? If you receive an offer for a free gift card that says "Participation Required" just hit delete.
