Definitely an interesting idea.

I had a similar thought when we were watching the Canadian trucker protest, and the subsequent mess around donations.

I thought, rather than a centralized donation point, and a mess around distribution, how might you just get a bunch of the protestors to create wallets and make them available for donations? You could easily split payments to each Lightning wallet.

The big problem here is verification of the destination wallets. How on earth would you stop random scammers from signing up for an airdrop every time there is a cause receiving donations?

On a small scale, this could work by someone lending their reputation. “I personally know these 10 Indonesians.” But in a large scale (a country, for example) I can’t work out how to solve that problem.
