Unsolicited messages, commonly known as spam, are unwanted communications sent via email, text, or social media. These messages often promote products, services, or scams and can clutter inboxes, making it difficult for users to find important information. Spam can be harmful as it may contain malicious links or attachments that can compromise personal information or devices. Many email providers and social media platforms have implemented filters to help reduce the amount of spam users receive, but it remains a persistent issue in digital communication.
