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 person outright rejects defederation as a solution when it IS the solution, if an instance is in favor of this kind of thing you don’t want to federate with them, period.
I also find worrying the amount of calls for a “Fediverse police” in that thread, scanning every image that gets uploaded to your instance with a 3rd party tool is an issue too, on one side you definitely don’t want this kinda shit to even touch your servers and on the other you don’t want anybody dictating that, say, anti-union or similar memes are marked, denounced and the person who made them marked, targeted and receiving a nice Pinkerton visit.
This is a complicated problem.
Edit: I see somebody suggested checking the observations against the common and well used Mastodon blocklists, to see if the shit is contained on defederated instances, and the author said this was something they wanted to check, so i hope there’s a followup
It’s the solution in the sense that it removes it from view of users of the mainstream instances. It is not a solution to the overall problem of CSAM and the child abuse that creates such material. There is an argument to be made that is the only responsibility of instance admins, and that past that is the responsibility of law enforcement. This is sensible, but it invites law enforcement to start overtly trawling the Fediverse for offending content, and create an uncomfortable situation for admins and users, as they will go after admins who simply do not have the tools to effectively monitor for CSAM.
Defederation also obviously does not prevent users of the instance from posting CSAM. Admins even unknowingly having CSAM on their instance can easily lead to the admins being prosecuted and the instance taken down. Section 230 does not apply to material illegal on a federal level, and SESTA requires removal of material that violates even state level sex trafficking laws.
