IPA: /ˈspæmˌbɒt/
KK: /ˈspæmˌbɑt/
A computer program that automatically sends unwanted or irrelevant messages, often in bulk, usually via email.
The spambot flooded my inbox with advertisements.
Spambot is formed from "spam" (originating from the brand name of a canned meat product, which became slang for irrelevant or unsolicited messages) and "bot" (short for robot, meaning a machine that performs tasks automatically). The word "spambot" refers to an automated program that sends unsolicited messages, typically over the internet.
Think of 'spam' as unwanted messages and 'bot' as a machine that sends them automatically — that's why a spambot is an automated sender of unwanted messages.
