Form spam refers to the unsolicited and often automated submission of irrelevant or malicious information through online forms, such as contact forms, registration forms, or comment sections. This type of spam is typically sent by bots or individuals with the intention of promoting their own products or services, spreading malware, or harvesting personal information. Form spam can be a nuisance for website owners and users alike, as it can clog up inboxes and compromise the security of sensitive data. To combat form spam, many websites use CAPTCHA or other security measures to verify the authenticity of submissions.
