You seem to think that the writer of this story is a "reporter." She's probably paid only to troll social media (in this case Instagram) and post clickbait that some readers might find titillating.
Why? The corporate media exists only to drive eyes to advertisers. Did you see how many ads there are on a typical nbcnews.com page? You were there, so someone probably made money just because the ads were visible to you -- no need even to click them.
