So it was brought up to me on post #6337482 by @Individual that key visual and other official artwork posted here should be tagged as second party or third-party sources as it's not from the artist's social media account. Would that be true, in spite of the artwork being meant to be posted on there instead of the artist's social media? If that were the case then would that warrant a BUR where most official art that isn't posted on the artist's Twitter or Pixiv accounts needing to have the tags implicated?
Usually I'd tag 2P or 3P sources on official arts only if the official art was taken from yande.re or other unofficial sources, and *maybe* the source tweet credits an artist that already have their own personal Twitter accounts.
