It's deceptive all the same, it's labeled "Sharing" when it really is providing content for them to monetize with no interest to compensate you in any way, which brings me to the other point.
Yes, it is true, people who find they need to feel like they are good at taking photos will seek out praise anywhere they can get it. And the sad thing is that what they think getting published means is gone, in the past. It used to be hard to get published and people got paid for it so it was looked up to...it was something to aspire to.
So idiot amateurs act like that it is still something to aspire to when it is simply not. All getting published means without monetary compensation today is that you got taken advantage of, your image was used for free and that promise of a photo credit being good exposure is worthless, all you are being exposed to is more Freetography™.
Amateurs who give their photos away for free are living a lie, they think it has to be worth something...anything and it is not, it is worthless.
