Ryan Jackson, 30, of Gaufron, Rhayader, was caught via his Facebook page during a joint investigation by Powys County Council and Sky.
Jackson’s devices were openly advertised for sale on Facebook for around £100, gave users free access to premium Sky content, including movies, sports and pay-to-view events.
Sky investigator David Ferguson made a test purchase and was charged £105 for a ’fully loaded’ Amazon Fire Stick which was subsequently delivered to an address in London.
The court heard that between January 2016 and August 2018, Jackson’s PayPal account was credited with £18,183.49 from sales to 84 customers.
Jackson pleaded guilty to three counts of selling devices adapted to circumvent technological measures, and a single count of breaching copyright for financial gain.
The judge imposed a fine of £1340, and made an order for £4070 in costs, plus a £34 surcharge.
