A Birmingham man who ran an online business selling fake exam and degree certificates has been jailed for three years.
David Fox, 51, sold the fakes - which included a masters certificate from Oxford University, GCSEs and vocational qualifications - through a website.
The trained graphic designer, from Coventry Road, Small Heath, was previously found guilty of four counts of fraud - two concerning him and two relating to his company Business Digest.
He had pleaded guilty to 12 counts under the Trademark Act and Copyright, Designs and Patents Act.
Sentencing the father-of-one to three years in prison at Wolverhampton Crown Court, Recorder Abigail Nixon told him he had damaged the "fabric of society".
She said: "In my view you were involved in a professional enterprise using skills you gained legitimately to carry out extremely convincing fakes."
She said she accepted financial problems drove him to launch the scam, but he could have found legal work or gone on benefits.
"However you decided to set up a sophisticated scam at your home address using these very, very effective skills you have to produce hundreds, if not thousands of disarming, convincing certificates.
"You even managed to gather together crests and signatures to match the institutions.
"The potential damage from your behaviour, your criminality, is immense and even now could have long-lasting effects on the employment market and fabric of society."
