Am UK but no it's not full of selling. There's obviously ads you can just swipe past. But the actual content I see is mostly amateur comedy skits, YouTube clips, standup comedy clips, fun facts and science, true crime, investment, conspiracies (would def get Zucked on IG), and random shit like that.

Algo needs time to learn your preferences but once it does it shows more of what you pay attention to.

And yes guys I know the issues of algorithmic social media, ofc, but TikTok does have good content.
