I was wondering about this with regards to bitcoin and other crypto currencies (which also have no way to choose whether or not to receive something sent to you). Surely someone could do some crime with coins in a certain wallet, and then transfer them to you; your wallet now contains illegal money and you don't really have a way to prove that you weren't involved.
