Tiktok
Usually social media is not a trustworthy source and that is not the first place you should go to for information. There was a study done by NewsGaurd, where they reviewed 500+ TikTok search results and found that 1 in 5 contained misinformation. This is false, sometimes dangerous misinformation that is spread by multiple people by mulitple people. In this case it was a video about Shein closing down, which is false, and the comments were flooded with messages like "thank you, your code worked!!" Meaning, this is a scam and the account wanted to make money.
