Duplicate Artist Commentary on multiple posts

I've sometimes seen that artist commentary was added to every post from the same source. So duplicate commentary across multiple posts.

What is the policy on that?
I think it usually just adds noise.

- With multiple requests for the same commentary, that can lead to duplicated translation effort.
- For a source with random pictures, the artist usually doesn't say anything interesting. It's often just "collection of pictures I had put on twitter".
- For a Pixiv post of sequential pictures, those pictures should be linked some way on Danbooru. Either in a pool or parent/child links. In that case, we can just put the commentary on the first picture.

Can the site be improved to better handle this?
For example, if Danbooru can determine different posts are from the same source, then it could automatically "link" the commentaries between them.

I typically don't add the commentary if it's just an image dump and the pictures are all unrelated.

If the pictures are related and become part of a pool, then I add the artist commentary to the sequentially first image added to that pool. So if there are multiple sets of images in a pool, in the case of chapters or whatnot, then the first picture in each set could have the artist commentary.
