The Bilibili App offers a service called "Card Collection Sets." It allows users to pay to draw digital cards from various gacha pools. These cards feature high-quality, often exclusive commissioned artwork as their card images.
Despite involving payment, I believe the card images themselves should not be considered Paid Reward, for the following reasons:
1. All card images are publicly viewable/browsable within the app for everyone, regardless of whether a user has paid to own the card. While the app doesn't provide a download button, the full-size images are publicly accessible via the image URL found in the webpage source code.
2. Each digital card on Bilibili has a unique ID and blockchain-backed metadata. They are transferable between users, making them true digital collectibles (NFTs). Users are paying for the unique digital collectible item, not directly for the artwork file. This is further evidenced by users potentially owning multiple copies of a card with the same artwork – they aren't paying per artwork view/copy.
However, since Danbooru strictly prohibits Paid Reward uploads, I want to confirm before potentially uploading any of these card images and risking a ban.
If uploading these card images is allowed, I plan to mass-upload them. These artworks are rarely seen on Danbooru or other boorus, so adding them would be valuable. If it's not allowed, I obviously won't upload them at all.
