It's time to start shunning these political donation organizations. Don't give them a cent - and eventually they'll die.

Verified PO Box + Cash sent through mail is the best short term fix. Just throw out the money changers.

In time, perhaps some sort of ZeroNet verification system could be worked out for charities. All the docs in one place, and all of that information impossible to censor. Only the poster of those files can remove it.
