Also, TIL the Red Cross is technically supposed to be the enforcer of these conventions.
Enforcing is the wrong term, as it is a humanitarian organisation. But the International Red Cross in partnership with its Palestinian Red Crescent counterpart is very much active in documenting these violations of the Geneva convention and working together with the ICC. Of course with the world being as it is right now the impact will likely not amount to much, but they are at least trying.
I don’t think such a website would see much use. Maybe better to contribute to an existing project that you are using.
