I would challenge that assumption as it goes. Here in Australia you need two forms of ID including a photo ID to open a PO box therefore it stands to reason that the chances of linking the rightful owner of the PO Box to an intercepted order is much greater than if something is just sent to a residential address given you can just say "I have no idea who sent that and it's definitely nothing to do with me". So I therefore fail to see the link between a PO box being more risky and attracting more attention, why would that be? Opening a PO box with fake credentials obviously increases your potential list of charges if you were to get caught using it or linked to it, therefore many people do not take the chance and just run with ordering to residential addresses including their home, which is if you ask me something that is far more risky than using an anonymous PO box not linked to you i.e. opened with fake documents. Sure the penalties are harsher if caught but the chances of getting caught are also much lower as you sever the link between you and the order. As will all things SR related it comes down to risk vrs reward, understand the potential penalties of the actions you are taking and make an informed decision based upon what you consider is acceptable or otherwise. Something to think about.
