Exactly. Positive is at best publication bias, or self-censorship, or whatever you want to call it, but usually it's pretty simply just fake.

People know it, but that doesn't matter, what matters is that people like those who live the high-life. Crystal clear ocean lapping the painfully white sand beach, the sky so blue, even its reflection seems to burn out as it shimmers on the endless cerulean horizon, all there for those who "have it". And the next post is a seemingly boring street, just shops, and our hero, somewhere in Europe, and maybe a messy hair day photo thrown in, our hero rests, somewhere in a 5 star hotel, a scantly clad young female caught an impromptu point in time, yet somehow critically perfectly advantageous for her, all of it - of course - done effortlessly. The next post is just a boring "shopping" pic again. Maybe a bag, a shoe, a dress from Prada, Gucci, Dior, but the 1000-3000 USD ones, of course.

So little said, everything implied.
