In the US, there are numerous states who require consent for recordings, so that may be another avenue.

When your income from Tiktok is tied to stream views etc., and you provide little journalistic content, you might have a hard time demonstrating that your stream wasn't "for commercial purposes".
The ASMP (American Society for Media Photographers) who work to protect the rights of photography among other things recommends that property and other releases be obtained if used for commercial purposes and states that in some situations, a release may be "required".
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).
