HappyBidDay.com is linked to BidCactus.com and Retailbidday.com. Penny Auction fraud.
So I fell for the Craigslist thing too, and got routed through several emails to the same message: "Hello Someone just purchased, but I can tell you where I got it from." Guess which site they directed me to? Any danger if I haven't bid on the site?
BTW, other names in the email tree, Tiha Anderson at *******@gmail.com, the infamous Diana Cyrus (or Jean Paul Centore) at *******@yahoo.com, pala at *******@gmail.com, and the original CL email, *******@gmail.com.
