In my opinion, TikTok is a network of wilful informants and a dataset that can be used to train AI at recognising foreigners so they can be more easily spied on when in China. It can also be used as a basis for race segregation programs and help run concentration camps in China (e.g. spotting "western" behaviour in the population and automatically issuing a ticket to reeducation camp). I think that service should be banned altogether.
