Mastodon, an alternative social network to Twitter, has a serious problem with child sexual abuse material according to researchers from Stanford University. In just two days, researchers found over 100 instances of known CSAM across over 325,000 posts on Mastodon. The researchers found hundreds of posts containing CSAM related hashtags and links pointing to CSAM trading and grooming of minors. One Mastodon server was even taken down for a period of time due to CSAM being posted. The researchers suggest that decentralized networks like Mastodon need to implement more robust moderation tools and reporting mechanisms to address the prevalence of CSAM.
The researchers can't be taken seriously if they don't acknowledge that you can't force free software to do something you don't want it to.
Even if we started way down at the stack and we added a CSAM hash scanner to the Linux kernel, people would just fork the kernel and use their own build without it.
Same goes for nginx or any other web server or web proxy. Same goes for Tor. Same goes for Mastodon or any other Fedi/ActivityPub implementation.
It. Does. Not*. Work.
