This comic is already fully translated, but not yet approved, would be a waste if it gets deleted because of that since someone already took the bother to translate it.
No it isn't. There were chinese duplicates that overlapped with the japanese versions in the same pool, thus the chinese was deleted. You can still see the entire doujin (the original was in japanese i guess) in the pool.
I think it's ok to remove the deleted chinese posts from the pool, so there won't be blank places anymore.
