Is Annas-archive legal in your country? Even if it is, is it moral? If it isn't, why are you comfortable breaking those laws, but when the time comes to support the site, and put your money where your mouth is, suddenly there are laws that are necessary to follow?
Morals are subjective, and this is not the place to preach. The charges for “donating money” and “money laundering” are absolutely worlds apart, and conflating them is disingenuous.
