YouTube is a bit stricter (though I don’t know Australian laws for sponsored content transparency); I watched their first UK vlog and it says nothing about being sponsored.They probably have a manager who has hooked them up with a travel company. If the places they are staying are labeled then it’s a good chance it’s #gifted. Tiktok is a bit murky for sponsored posts.
They have three 15-20 minutes vlogs out already about the UK trip. Now that seems like something an agency/management company would do for them, because with all the traveling they’ve done, I don’t know when they had time to view, edit and release their footage. Or maybe I really am underestimating these girls.
