do you think this is a scam?  

I know what you mean and have been in this kind of situation all the time. I sign up for survey sites and freebies all the time but junk mail and spam comes along with it. After viewing the link YES it is spam and I would just delete the emails. Ive seen these all the time if the prize is unbelieve such as a simple $500 GC its SPAM. A lot of people will fall for these kind of scams all the time. Also, if you read the print at the bottom you must qualify and finish promotions before being considered which you have to pay for these promotions. We actually did this for a class project and after you pay for it they take your money, and just lead you to a dead link or some other useless scam site.

Are you making people fool?

Definite Scam!

Scam in a way, it will give you some offers to sign up and initially they have the skip option but while reaching end, its made compulsion to accept offers, something like
-two silver
-one gold

offer to get what you signed up for, I tried many such site and never got anything as I never paid for silver and gold offers

don't waste time on it

Will say, better head to my profile and join the link which says 4- Pays 50 cent per referral. That site is quick and easy to earn at and is open for members all over the globe.

Good Luck
