The phrase points to software or services designed to artificially inflate the number of individuals subscribed to a YouTube channel, often involving automated processes for acquiring these subscriptions, and potentially the act of obtaining such a tool. An example would be a program advertised online, promising a significant increase in YouTube subscribers after being downloaded and installed.
The existence of such tools highlights the perceived importance placed on subscriber counts as a metric of success or influence on YouTube. While a higher subscriber count can create an impression of popularity and potentially attract more viewers, the use of automated methods to achieve this is generally discouraged and can violate YouTube’s terms of service. Historically, the pursuit of perceived online influence has driven demand for these types of artificial augmentation techniques.
