One of the major reasons humanitarian organisations are not attacked or even protected is because generally they provide benefits impartially, officially or otherwise. This makes attacking them "spitting into the well" and risk not only depriving yourself of the benefits but also earning yourself enemies from all sides.

I don't believe this dynamic exists online, for one, the belligerents are often in the shadows and don't depend or rely on any "community" or locality that might be benefiting from humanitarian work.

The only benefit this digital certificate might provide is prosecution grounds for harsher punishments, which isn't useless, but far from being a red cross or lion.
