In today's digital age, receiving unsolicited text messages, commonly known as robotexts, has become a prevalent nuisance. These messages often come from unknown numbers, promoting products, services, or, worse, attempting to scam recipients. Fortunately, several applications are designed to help users filter and block these unwanted texts effectively.
What Are Robotexts and Why Are They a Concern?
Robotexts are unsolicited text messages sent in bulk, typically for advertising or fraudulent purposes. They can range from legitimate promotions to deceptive schemes aiming to steal personal information. The Federal Communications Commission (FCC) reports that in 2023, Americans received over 13 billion robotexts in April alone, highlighting the scale of the issue. (sorensen.house.gov)
