Regarding when I want to upload images from Pixiv, do I have to ask for permission from the artist to upload his/her works here in Danbooru? Or can I just freely upload them? (first time uploading anything here)
When uploading directly from pixiv (putting the image URL in the Source field), click the Artist button next to the Source field. If the artist is banned (the artist directly contacted Albert and asked to have their works removed), it will say so in the Related Tags box below.
