I know, but TFA says that some of the people recording are coming from Europe.
Seems kinda silly to enforce a country's laws on someone even when they're in another country. I guess social media makes it kind of a gray area though, since the violating act might be the upload itself (which can happen anywhere and is essentially 'continuous' even when the uploader returns to their home country).
It's relatively common these days. The US assumes global jurisdiction for anything that touches the US Dollar (as e.g. Kim Dotcom of Megaupload has been fighting for years now), and most Western nations assume global jurisdiction for a select few grave crimes (mostly murder, war crimes and sexual exploitation of underagers).
