I've often thought an authenticated proof of donation to a global charity could be a solution to these types of problems, scaled in price to the senders locale.

Not refundable, but at least a donation to UNICEF allows the receiver to impose a submission cost without the implication they are doing so out of greed.

This is a very good idea. Offering authenticated donations could be a good revenue stream for charities, too.

Plus, the required amount could be adjusted based on origin country. $0.10 for you, $20 for that guy.
