Get £750 for shopping at SHEIN

Insta $750 Shine Gift Card, Scam or legit? What will happen?

We all know about the ads on insta of the $750 PayPal, Cash App, or now, Shein. Many meme accounts post a link in their bio to get the $750 gift card, when you click on it there are three questions, "Do you shop on Shein?" "Yes" or "No" "How do you plan to use your $750 Towards Shein?" "Keep" or "Give to a friend" and "About how many times do you go shopping per week?" "<3" "3-7" "7-10" or "10+" Then it asks for your e-mail. My question is not only If it's real? but if it is/isn't, what happens when you give your email? I'm getting mixed answers when I go to look it up.
