Snowshoe spamming refers to the practice of sending a large volume of unsolicited and often irrelevant messages or advertisements to a wide range of email addresses, in order to bypass spam filters and reach a larger audience. This term is derived from the idea of spreading a message like a snowshoe, covering a large area and leaving a trail of unwanted messages in its wake. Snowshoe spamming is often used by spammers to evade detection and increase the chances of their messages being seen, but it can be a nuisance and a security risk for recipients.
