The bulk update request #240 has been rejected.
Similar to how loli is hidden/restricted behind a setting, there are bunch of oppai_loli images that are definitely young enough to be considered loli (as it is right in the name), they just have the unrealistic aspect of having larger breasts than what a child can have. But we are already talking about fictional characters here and just like big feet wouldn't disqualify post being a loli, big breasts necessarily shouldn't either as flat chest is not the only thing what makes loli a loli.
Benefit: Most likely people who don't want to see loli on their pages, don't want to see oppai loli either, so this implication would fix that.
Disbenefit: People who like loli but not oppai loli will see the posts. I think the simple solution for them would be to just blacklist oppai loli.
Before this BUR would be approved or rejected however, I think it would be the best to discuss if all the posts currently under that tag are even loli. If we want a implication between them, we don't want any posts that are not even loli to be auto-added because of the implication.
Here's the Danbooru's side of discussion about the very same implication.
