Well I'm sold for $100 to Oxfam America. Confirmation below. If someone tops it and calls me a sissy, I'll try to restore my dignity. It's bullshit, people who donate to these organizations should be able to opt into a publicly accessible database of donations. If people are serious about the causes they'd do it regardless of how much they donate, because they'd know that overall more visibility and verifiability will produce more donations.
