Correct me on any side of this sentence:
"Your project is aimed to provide a safe and secure way of an image creator --which on its category, a photographer-- to publish and get loyalty of their works, privately."
So if someone uploaded a selfie images, or an image with certain identifiable object or subject on it, intentionally or unintentionally, what then?
Why would anyone upload selfie in CC0 license photo sharing platform ..
Because they think its beautiful, the background are nice, the tone is just perfect, etc? Who knows? Don't you consider that as a possibility? Even one in a thousand chance? And don't you think about a prevention for such scenario? No matter how less likely --but still had a probability-- it'll happen?
There are three steps of uploading photo.
1. Image Uploaded by user.
2. Approved by Moderator.
3. Finally published in Itsfoto.
If photo is according to the terms of site then only it will get approved by moderator.
That solves the problem.
On to the next one, what's your plan for the case of copyright? I mean, due to annonimity, how likely is it for the following scenario, and what's your solution for such:
A photo being anonymously uploaded --and made it rather difficult for someone to claim the true ownership-- and many people buys it, and at one point, someone claimed it as theirs, only it wasn't. And someone else also claimed the artwork as theirs, and so on and so on.
because i think its clear to you the meaning of "original work" and "derivative works"
