Nah, this is two things: Ostensibly it's a link to a real identity. This is something that social media always struggles with and money —any amount— always seems to be the leveller. Until bots can register their own credit cards, this helps prevent spam, abusive posting, account cycling and a host of other nasties. But I suspect the true aim is getting a foot in the door. Once they've saved your card details, future billing gets super-simple. Activating trials of Blue and micropayments for small oneshot promotions, even silly little things like super-likes. But they're not going to stop seeking advertisers and using what they know about you to link the two. If anything this just gives them more data points.
