WhatsApp used to charge $1/year before the Meta acquisition. If you could convince people to pay $3/GB, that'd be enough to front the content with Cloudflare and store the data in the Internet Archive forever. Still need to solve the moderation problem, but it isn't impossible.
If people are paying to host the material, isn't what they host on them?
You could even have a lawyer add something like, "You are purchasing hosting rights for yourself and therefore take all responsibility for what you host. We will work with any relevant government authorities whose jurisdiction you are under to provide them information of your activities on this service if the products you provide violate local, state, or federal laws. You agree to post nothing illegal and if you violate that you agree to own all responsibility, legal, personal, or financial, for your posted materials... blah blah blah"
And then submit everything posted to csam scanners.
> We will work with any relevant government authorities blah blah blah
the problem is that costs money. you either pay the staff to do the moderation at upload, or you pay the staff to handle all the various governments that come after you. either way it's expensive, but dealing with the government's lawyers is probably more expensive. and no, just running through a CSAM scanner isn't nearly enough.
