They just want your government id. It makes their data set more valuable to advertisers. So the extort it out of you after you're partly invested in the platform. The security thing is just cover. That is why they often demand your phone number later too. If the demanded it during signup you'd know the deal you were making and would probably back out. So they do it after you're invested so you have something to lose instead of them.
