Jacmob began 'full-time' employment at Jagex whilst at school, and continued during his degree programme at the University of Cambridge. He would fit in his work when he had time around his degree, but had some involvement in almost every Jagex product and service. He is best known for his work on the Bot Watch system from 2012-2014, and the internal procedures for its use. During his time overseeing Bot Watch, waves of bots were consistently banned from the game making sustained bot use infeasible.
