There are webcam feeds all over the earth, most can be found by just scanning ip addresses. There are even websites dedicated to finding them. You’d probably have a better dataset than TikTok simply because it is more realistic. The best part: it is free.

No you said a comparable dataset to TikTok was commercially available.

Few random webcams which would be illegal to take video from is not substantive and does not provide any insight into their interests, likes etc.

The whole issue with TikTok is that the Chinese government is able to personally identify people who disagree with them.

I’m not in the business of selling datasets. But it also sounds like you don’t know what problem you’re actually trying to solve yet. That’s a problem I can help you with.
