Subscription form spam refers to the unsolicited and often automated submission of multiple subscription forms with the intention of flooding an individual or organization’s inbox with unwanted emails. This type of spam is typically used by marketers or scammers to promote their products or services, and can be a nuisance for recipients who are bombarded with irrelevant or misleading content. It can also be a security concern, as these forms may collect personal information without consent. To combat subscription form spam, individuals and businesses can implement spam filters and regularly review and update their subscription lists.
