How many people have created and published videos on YouTube and got maybe a few tens or a couple hundred views over years.
TikTok new users gets a couple THOUSAND views and the user is like "people like my content I MUST make more!!" And now they're hooked trying to get the same high view count as before.
I would assume (as I have never used the platform) it's also a way for TikTok to grab you financial information "you earned x$ from you first video, please supply you financial information and a scan of your ID for payment.
It's an addiction.
