new scam 2027

There is a company that promises to give Amazon gift vouchers when you mention their name "zoullu.net" and share this post with 5 people. Their system automatically knows that you have shared it, and they even contact you by message or call and give you the voucher. I tried a purchase on Betclic, it works fine but strangely I'm not convinced. I'm a bit scared. Has anyone here heard about this before, please?
