basically it goes over the whole process in general, and each country enforces and has laws of various degress on it. For example, with console dumping and flashcarts int he US are deemed illegal. Nintendo has already sucessfully shut down some stores that offer modding services without even necessarily offering up the illegal goods. Flash cart companies online already go through lengths in order to help the customer “avoid customs” as flash carts legally speaking, aren’t legal to buy in the U.S, and normally is supposed to be confiscated at the border. Not all agents are aware of it though as it’s not as strictly enforced and known like drugs or weapons would be.

It’s a field where not many want to challenge said law.
