It makes sense to want to donate to a dom bank but it would be kind of weird as long as Shadow doesn't make a public statement on it, doubly so if you're not in Shadow yourself. It would be a different case if you're a flight member and the dom team is asking for fundraising efforts. But if that were the case, the thing that would make the most sense is to sell it at whatever price to the public, a slightly discounted price for Shadow members, and afterwards donate profits to the bank.
