This is a reach, but is there such a thing as "intro to money laundering"? It's such a fascinating topic, but every time I come across something that teaches me something they are super sparse on details, because they don't want to give the bad guys ideas. (As if the fucking bad guys need ideas.)

The most interesting thing I've read about is money laundering by selling in-game items in MMORPGs, since there's no physical product that needs to be accounted for. But would be interested to read more about this topic.
