How about this for everyone: regardless what you think about money laundering, if a financial institution in the US doesn't have the proper Anti-Money Laundering (AML) checks in place there are HUGE fines and legal trouble. Ask any bank or broker. Once groups start using your cards as a way to send money to their people inside, you'll have all kinds of new friends in the government.

At that point, your ethics are no longer up for debate and the law is coming for you.
