I know that the largest charitable donations (not going to server fees but going to causes like the Japanese earthquake appeal) goes over four digits.
Going off in a tangent here, but are we dumb for not using that money directly to help the girls by purchasing CDs or gifts for them? I think not. Because SONE don’t care about buying records or winning awards as much as doing good things in the girls’ name.
That’s why we donate blood, that’s why we “waste” fandom money, that’s why we stand by the honourable causes that they champion.
