What term describes unsolicited SPAM sent over Instant Messenger platforms?

The term that describes unsolicited spam sent over Instant Messenger platforms is known as SPIM. This term is a combination of "spam" and "IM" (instant messaging). Just like traditional email spam, SPIM consists of unwanted, often irrelevant promotional messages sent to users through instant messaging systems. SPIM can be particularly intrusive, as instant messaging is typically used for personal or immediate communication, making unwanted messages more disruptive to users.

In contrast, SPIT refers to spam over Internet telephony, focusing on voice communications rather than text. Vishing is a form of phishing that uses voice calls to trick individuals into disclosing personal information, while phishing generally involves fraudulent emails or messages that aim to deceive recipients into revealing sensitive information. Understanding these terms helps clarify the specific nature of various types of unsolicited communications.
