EBay's decisions are not only silly they are slapdash. No effort is expended to determine what unintended effects their policies generate. Even a barely competent programmer could write the parameters of the Cuban stamps ban to narrowly target only the sales of those items whose sale directly benefit the current regime.
If a Cuban stamp that was issued five years ago is sold by a stamp dealer, the regime does not benefit because its financial interest in the stamp ceased the moment it was sold to whomever. Of course you could spend 100,000 years fruitlessly trying to explain that to eBay middle managers.
