What is the cheapest, most user friendly way to document crimes of a government regime on an immutable blockchain?

I'm curious what are the best ways to easily publish immutable data that documents international crimes using names, dates and photos such as base rules or other means to ensure that authoritarian regimes are eventually held accountable.

For example, how would journalists post articles on web3 in this way and how would every day people read these posts?

How would the host this data anonymously?

How would projects like this get funded?

It seems abundantly clear to me, that with the USs failing democracy, there will eventually be another Nuremberg Trial and in this age, if there isn't already, there must be such a platform to be used for such a trail.
