To your point, TikTok is filled with absolute trash.
For example, there’s a company called “Cerebrum IQ” which scams people out of hundreds of dollars for fake IQ tests. We are painfully aware of this issue because we own cerebrum.com, and we receive at least 100 furious support requests per day from people who have been charged $80.00+ for a subscription they never agreed to, and they somehow confuse us with “Cerebrum IQ”.
They get most of their users from TikTok ads.
We’ve reported them to TikTok many times, with no action taken. Meta at least restricted their ability to advertise.
