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.
