Johnstone admits at his Durianrider Publications site that he sources his framesets from a Shenzhen supplier. In what appears to be an amateur-hour drop-shipping endeavour, Johnstone takes your order - and your money - and then relays the order details to the supplier. The supplier will then send the frameset to your address. Johnstone is charging naïve buyers hundreds of dollars extra for something they could easily do themselves.
Furthermore, because they are buying through Johnstone, buyers of his framesets will need to deal with him in order to settle any purchase or warranty issues. Potential buyers should know that diplomacy and tact are not Johnstone’s strong points; his standard procedure for dealing with disputes is to fly into a rage and start behaving like an unhinged madman.
Johnstone has a long history of dishonesty, stalking and threatening behaviour. Below is his rap sheet, which shows Johnstone's malevolent behaviour stretches back decades. A restraining order was placed upon him in 1995, when Johnstone was 18 years old. He has also been prosecuted for damaging a vehicle owned by a public transport company and for failing to pay fees owed to a medical diagnostic company.
