Some images on the site may be considered unsafe for certain ages and people. They may contain nudity and other sensitive material and therefore we don't display them by default.
You can choose to show or hide this kind of content. If you choose to hide it, you'll see an image with a warning message instead of the unsafe image. If you choose to show it, you'll see them no differently than regular (safe) images.
