FOR YOU.
What TikTok chooses to show you is extremely personalized, I have never encountered any of the live streams you describe above.
I mostly get young good-looking guys trying to promote their OnlyFans.
...and I don't think most people on TikTok get livestreams like that, so I would be very cautious about making any sort of sweeping statements of what the experience will be like for other people.
That said, I'm absolutely delighted about all the absolutely crazy things and the enormous diversity of stuff you can get on your feed. TikTok feels just like GeoCities did on the early web, it's a bazaar of the bizarre, and trends change so fast that you never get bored, and corporations still haven't been able to suck the joy and life out of the thing yet.
