* Blacklisting: People who were suspected of being communists or having communist sympathies were often blacklisted, which meant that they were denied employment in their chosen field. This had a profound impact on people's lives and careers.
* Intimidation and harassment: Suspected communists were often subject to intimidation and harassment by government agencies and private organizations. This included surveillance, questioning, and even threats of violence.
* Detention and deportation: In some cases, suspected communists were detained or deported. This occurred both in the United States and in other countries.
