The project is interesting, because now there are not many such platforms where you can upload photos almost for free. And the main thing is that it will not lose quality and the platform is completely anonymous, this is a good plus to the project.
Well, I think it is not necessary to hide your identity if you upload beautiful and high-quality photos of nature, for example. Anonymity on this platform is hardly necessary for someone.
Based from what I understand, it's the transaction that is anonymous because they based on the cryptocurrencies. People who upload the photos definitely be visible but the payment is said to be anonymous.
