Suppose a user uploads a Pixiv post from an artist who isn't part of the banned_artist category, nor does the latter have any outstanding requests against Danbooru. The artist then requests Danbooru to take down his art at some point in the future. Do the banned posts count against the uploader?
I mean, I can understand that if a user uploads art that is from an artist already listed (at the time of uploading) in the banned_artist category, then it should count against his record, to discourage such practice. Uploaders should conduct due diligence before uploading images, after all. At the same time, uploaders can't predict if an artist will request for a takedown later, so counting images that are banned later against a user's record does seem a bit unfair (assuming the artist wasn't 'banned' at the time of upload), and has the potential to nuke a user's upload limit (or at least leave an indelible mark) if he's a fan of a particular artist and uploads almost exclusively with art from said artist.
