What is indicated by the term SPIT?

The term SPIT stands specifically for Spam over Internet Telephony. This refers to the practice of sending unsolicited communications, typically voice calls or messages, through Voice over Internet Protocol (VoIP) systems. SPIT is particularly concerning because it can disrupt regular communication and potentially overwhelm networks, similar to how email spam disrupts traditional email systems. Given the increasing use of VoIP technologies, understanding and identifying SPIT helps in recognizing one of the evolving threats in the digital communication landscape.

The other options, while related to spam in different contexts, do not accurately define the specific term "SPIT." For instance, spam targeting specific individuals might refer to a broader category of phishing or targeted email attacks, but it does not capture the essence of spam in the realm of voice communications.
