No, it's not hypothetical, there's a handful of those images embedded into bitcoin forever. I found this reference for you: https://fc18.ifca.ai/preproceedings/6.pdf https://fc18.ifca.ai/preproceedings/6.pdf See under "Illegal and Condemned Content": > Bitcoin’s blockchain contains at least eight files with sexual content. While five files only show, describe, or link to mildly pornographic content, we consider the remaining three instances objectionable for almost all jurisdictions: Two of them are backups of link lists to child pornography, containing 274 links to websites, 142 of which refer to Tor hidden services. The remaining instance is an image depicting mild nudity of a young woman. In an online forum this image is claimed to show child pornography, albeit this claim cannot be verified (due to ethical concerns we refrain from providing a citation)." I'm sure if you really put your mind to it, you could find and recover the images, but then you'd just have illegal content and that's not very useful, so why dig for it?
