This is called private information retrieval. So, you think that if a pedophile accesses CP via PIR, it is okay? Because it is impossible for the uploader or anyone else to know if anyone requested to download the CP, so the demand for CP in a PIR distribution network can NOT directly lead to more production, as it is impossible for anyone to determine ANY INFORMATION about the demand for CP via analysis such a system.An interesting notion isn't it? Does anyone know if this is how CP sites work in practice? For example is it possible to leave comments on videos and images even if it's not possible to know how many people have downloaded them?Do you think it would be also possible to get an idea of the popularity of material you've uploaded by seeing it hosted on other sites or would material shared in this way be downloaded centrally?V.I am not aware of any CP distribution taking place over PIR, although OFFsystem might qualify for that, I know little about OFFsystem though. I am not saying this is how CP distribution today is done, but I am saying that if your primary issue with CP viewers is that the demand they create leads to production, then that issue would be solved if distribution took place over a PIR system. If the possibility of determining popularity of material by uploading to non PIR distribution mechanisms exists, then that would only apply to people who are actually uploading content. So still, your major gripe with CP is addressed in a world where all CP transfers are done via PIR. And you are left only being able to use your 'demand leads to more production, so should be banned' argument against people who upload or download outside of the PIR.I suppose my concern would be that even if you used PIR users would learn of the popularity of their content vicariously by comments left on videos/images or mirroring on other CP sites.I appreciate this is ducking the issue however - let us imagine a system whereby a person could upload such content and have no idea who was watching it, would this then ethically absolve a downloader of any moral responsibility for viewing it?If you don't mind I'd like to take some time to mull this over before responding in full, speak soon!All the best,V.
