I'm pretty sure GiselleBot used this NSFW model and yea, not a good result

Start by reviewing the linked Streamable example and reproducing its classification with the NSFW model. Compare the result with the reported GiselleBot behavior, then determine whether the false positive is reproducible and what model or data change would be needed; done means the black-and-white manga example is no longer incorrectly flagged.
