Spam calls are unsolicited phone calls made by telemarketers or automated systems, often trying to sell products or services. These calls can be annoying and disruptive, as they frequently interrupt daily activities. Many spam calls use tactics like fake caller IDs to appear legitimate, making it difficult for recipients to identify them as scams. To combat spam calls, various tools and apps are available that can block or filter unwanted calls. Additionally, government agencies like the Federal Trade Commission (FTC) encourage people to report spam calls to help reduce their frequency.
