A post whose thumbnail is misleading; it looks like one thing at first glance, but something else entirely once viewed in full size.
This is generally for thumbnails that are unintentionally misleading by the artist, not for intentional thumbnail surprises, optical illusions, photorealistic images, or sexually suggestive situations.
Don't add a post just because it has a colored border that corresponds to the ones used by Danbooru, including a blue, red, black, green or yellow border.
If necessary, please explain the misleading part of the thumbnail in the comment section.
