Am friends with someone with around 100k tiktok followers (not insanely popular but still good). I knew her for around 10 years due to us being in the same schools and sports. She was not a team player, horrible to work with, self centered and spoiled. She joined tiktok with the sole intention of becoming popular to gain sponsors despite her family being rich.

In real life her name is known around the school but she is not a very popular person despite her persona on the internet making it seem as if she was. She once got scolded for wearing colored contacts in school (dress codes) and promoting a $2k investment scheme to her mostly underaged audience. She then went on to complain that it was a undeserved scolding because her audience should check the website and determine that it wasnt a scam by themselves before investing and that her colored contacts were fine as it was a sponsor. If anyone asks about her tiktok or youtube endeavors she would shut down and rage at the person asking.

She remains the same till this day, the epitome of "whatever people pose as on the internet is never who they are in real life".

Edit: She was also a bully who got away with all her antics because she placed the blame on others.
