Images can be blocked depending on the level of violence or nudity detected in the image. When you upload an image to a thrill post, you'll see an "Analyzing Thrill" message. During this process, referred to as "image detection," we'll scan the image to identify content that is likely to be blocked, such as excessive violence or nudity. If your image is blocked, it is likely that an inappropriate level of violence or nudity was detected in the image.
