What if your video is outside of the US? We did a few hotel stays in exchange for a video. Is it a problem if they are in Nepal? The value was always under $100. I can take each video down and update it, but I'd rather not if it's no big deal for unmonetized channels in Asia, although I am from the US.
The FTC is a US Government institution and has no authority to enforce laws in other countries. However, they do have authority over YouTube because YouTube is an American company. I doubt very seriously they are worried about you doing a hotel review in a foreign country. I think a lot of Tubers get such perks once businesses find out they are tubers. I would not worry about this.
I have built a well-known brand around Jungle Explorer that covers way more than YouTube. I have secured accounts under The Jungle Explorer all over the internet for the last 20 years. Facebook, Twitter, Instagram, TikTok, Google Local, Yelp, TripAdvisor, etc. If a business finds out who I am when I am there, they will seldom charge me for service. I never ask for it, but they just refuse to let me pay. So, I have to be very discreet about it to preserve the integrity of my brand, which is about honest reviews. It's kind of like being a food critic. But also, I like to promote small local mom-and-pop businesses, if they are doing a good job. So, if a new local restaurant opened up, I will go to them and do a free professional style photoshoot of their establishment and their dishes, and create their listing with the top review sites like Google Local, Yelp, and TripAdvisor. So many small businesses don't even know how to do this, and it is really a shot in the arm for them to get them started off running. Of course, these businesses know who I am so, when I visit them, I get the red carpet.
