To let others verify the correctness and quality of images, whether they're free or paid rewards, please supply the official sources for any uploads. For example, if an image comes from Fanbox, please provide the link to the Fanbox post that publishes that image.

[UPDATE] More about how to provide a valid source:

• For images from Pixiv, please provide the direct link of the image itself as the source (as clicking such link will be automatically redirected to the Pixiv page the publishes it).

• For images from other sites, please provide the link of the page that publishes them.

• For isolated pages from books (not more than two pages from the same book uploaded) and cover illustrations from ASMR works, it's OK supply the title of the work in question instead of a web page link. (Note: If uploading more than two pages of images from the same book, please also create a Pool for them.)

• If it's unable to supply a valid source (e.g. image was distributed via a DM instead of being published in a certain page, or the official link is in hand but it's no longer available due to deletion by the artist themselves), please supply the nearest thing known as the source, and write down what happened in the Comments of the Post in question. (Note: For works published via DMs, in addition to providing explanations in the Comments, the link to artist's Profile Page of the site such DMs were sent may also be used as source temporarily.)
