Answer: It depends on what they did and why they did it
Step-by-step explanation:
A good example of someone whom shouldn't have had such a treatment is Corey Feldman (who tried to reveal how hollywood treated actors). Whenever someone has something personal happening or is in a bad mental state, the public takes that as a threat because one needs to fall into line with the publics thoughts. When one has more power than the average person and more of a public image that can be damaged easier because of an action, they have to be very careful to keep it from crashing down because of an action. One should be cancelled if
1. They said something very rude to another or acted negatively to another
2. They lie to the public or lie about another person/Scam the public into buying something from them or a corporation
