There’s been conflicting research into how internet users will react to a letter from their ISPs warning them not to file-share. Some insight into how hardcore P2P users would react is provided by a survey on blog TorrentFreak, which asked its readers what they’d do in event of such a warning.41% said they would take steps to conceal their identity using a service to hide their IP addresses – examples being BitBlinder and The Pirate Bay’s IPREDator. Only 7% of respondents said they would stop file-sharing.Bear in mind, of course, that TorrentFreak’s readership are more likely to be pro-P2P and fairly tech-savvy, so these results aren’t indicative of the wider population. In that light, it’s more evidence that the warning letters strategy should probably be judged on its success in deterring more casual file-sharers.
