TikTok is allowing users to spread manipulated videos of Biden, despite the platform's policies

I never used TikTok so I'm commenting on the assumption that now things are the same everywhere.

I can believe that there is a lot of manipulated content. But then when it comes to decide which content is manipulated and which isn't most of the time the decision is the opposite of the truth, except for that content manipulated on purpose to provide the false alternative and trap the discussion between two falsehoods.
