Karl Jobst (born 7 February 1986)[3] is an Australian YouTuber, investigative journalist, and GoldenEye 007 and Perfect Dark speedrunner, whose work has primarily focused on exposing cheating and fraud in the gaming community.

He briefly studied IT and psychology at university and spent time working at a chicken factory, a mobile phone shop, and a call centre.

This feat was described by Owen S. Good of gaming magazine Polygon as "akin to the sub-four[-]minute mile, multiplied by breaking the sound barrier.
