yandere sample
This tag indicates that an image from Yandere is not the full size image.
It is Danbooru policy to either replace samples or delete them. See image sample for more information. See howto:yandere for how to upload images from Yandere correctly.
Note: One caveat to the above policy is if the fullsize image is greater than 50 MB, the upload limit on Danbooru.
