idk if its a scam, but whoever "developed" this, must be a very sick psycho. I tried to sign up, and there was a recaptcha on every freaking page. It doesn't matter if you solve it, next page you will get another captcha. At one point you get very complicated captchas to solve, just for the fact they use it everywhere and Google starts to think you are a bot. And a security pin which is basically just another password, not a real pin that you get sent to one of your devices. Jesus Christ, people who use their site must be massochists to endure such a bad interaction with the user.
I notice this captcha trend used by anyone for anything but this is just crazy. And for no benefit, because even the most incompetent "hacker" can buy 5000 captchas for a few bucks from at least 5 different recaptcha-solving sites..
