Vallor had attended Ysgol John Bright in Llandudno and left after his GCSEs.
Later he became a warehouseman and worked as a website designer at The Cottage Loaf pub in the resort. His crimes stemmed from his terminal in his living room.
With short, spiky hair and dressed in a brown tracksuit top with white lines on the sleeves, flared blue jeans, blue trainers, he straddled his computer chair, the wrong way round, and set about explaining himself.
Simon Vallor, a website designer, said: "I had the usual PCs - Spectrum Sinclairs - and upgraded the powerful Commodore 64. We didn't have one for years after that, just the basic PlayStation.
"I got a computer again when I was 15, 16. It was a family computer to enhance everyone's IT awareness.
"The Internet is the biggest communications tool in the world, regardless of the telephone. You pay £50, £60 for a good book. Why pay for that when you can find that information free on the internet and have it validated by billions of other people?"
Vallor said: "School bored me. I don't like being sat down. People telling me what I'm going to learn. Our school IT curriculum was pretty basic.
"I don't know whether I'm quick, I'd say persistent. If I want to learn anything I won't stop till I've mastered it all, till I've found something else to master. It's what I enjoy doing.
"Since I've had a compiler on my computer I've always been interested in programming. You start with symbols and at the moment I'm working on a low level language. You can't get much more down inside the computer than if you were writing in zeros and ones."
He puts his fascination of computers partly down to losing his mum. Maureen died from a heart attack on holiday in Benidorm in 2001.
He said: "Once my mum died I started spending most of the day, and I mean most of the day, I was sleeping four hours a night if that and most of the rest of my day was spend on the computer. I wasn't going out at all. I was coming out of bed, on the computer, back to bed back, back to the computer.
