This isn't actually all that new of a phenomenon. People have been busted for scanning manga images for net cafes and numerous Japanese were arrested off WinMX and winny for distributing software.
Though it should definately give some ex-pat youtubers and raw-providers pause. The LAST thing most fans living abroad want is to be deported permanantly.
The focus is on domestic piracy... but one look at youtube gives you about 600 links to raw anime epsiodes uploaded by foreigners either living in Japan or the US which are available to Japanese youtube viewers (and companies likely to sue your pants off for distributing them).
It's actually one of the reasons I dislike this site's gallery being open to the public and spiders. If someone wants to go after me for uploading all those scans after a simple web-search for their property: I'll probably be sent packing for good. And as unlikely as that is at this point in the game, it would really suck to be "the example".
