Warning letters from broadband providers do nothing to dissuade illegal file sharers.
That is the conclusion of a new study conducted by legal firm Wiggin, which revealed that just 33 per cent of those downloaders questioned said they would be deterred if they received a letter from their internet service provider (ISP).
This year's Digital Entertainment Survey involved 1,500 people and was conducted in association with paidContent:UK.
According to the study, 80 per cent of the respondents said they would stop downloading if the letter was followed up with action such as the disconnection of their internet service.
Alexander Ross, partner in the media and technology group at Wiggin, commented: "A letter would not be enough. It does take an ultimate sanction."
The research is in contrast to the findings of the 2008 Digital Entertainment Survey, which suggested that 70 per cent of people would stop downloading if their ISP sent them a warning letter.
