Through Embryo, Moore became involved in a group known as the Northampton Arts Lab.
The Arts Lab subsequently made significant contributions to the magazine.
He has occasionally used such pseudonyms as Curt Vile, Jill de Ray, and Translucia Baboon; also, reprints of some of his work have been credited to The Original Writer when Moore requested that his name be removed.
The headmaster of the school subsequently "got in touch with various other academic establishments that I'd applied to and told them not to accept me because I was a danger to the moral well-being of the rest of the students there, which was possibly true." Whilst continuing to live in his parents' home for a few more years, he moved through various jobs, including cleaning toilets and working in a tannery.
In late 1973, he met and began a relationship with Northampton-born Phyllis Dixon, with whom he moved into "a little one-room flat in the Barrack Road area in Northampton".
Not long after this, in 1979 he also began publishing a new comic strip known as Maxwell the Magic Cat in the Northants Post, under the pseudonym of Jill de Ray (a pun on the Medieval child-murderer Gilles de Rais, something he found to be a "sardonic joke").
Earning a further £10 a week from this, he decided to sign off of social security, and would continue writing Maxwell the Magic Cat until 1986.
His first paid work was for a few drawings that were printed in NME music magazine, and not long after he succeeded in getting a series about a private detective known as Roscoe Moscow published using the pseudonym of Curt Vile (a pun on the name of composer Kurt Weill) in the weekly music magazine Sounds, earning £35 a week.
