Guys are giveaway sites TRUE or SCAM?

I found several sites that are for giveaways, one is giving an iPhone 11 PRO MAX, the other is giving MacBook Air last Gen, You can join that giveaway for 1-5$, but at first, you have have to fill a blank about yourself, Is it to collect data, or to know where to send the prize?
Also, I heard that is good for business, but I don't know how good is it?

Any answer is welcome.

Giveaway websites are generally fake if they ask you for an extravagant quantity of information. That said, there are lots of giveaways here, and websites like Gleam are legitimate.

Its for data mostly though

Giveaways that redirect you through several websites are complete scams. If you give them your real information, it will certainly be used.

Also, if you have to pay to join a giveaway - it is not a giveaway, it is gambling.

Thanks for the info mate.
