I would like to hear from somebody living in a country that already has this kind of system in place. How does it work in practice? Do they catch every torrent you download for instance?
In France, "95 percent of people who have received a first-time notice of illegal sharing 'do not give rise to the need for a second notice,' that 92 percent of people who received a second notice cease illegal sharing, and that 98 percent of people who receive a third notice 'show the same trend.'" http://www.theverge.com/2012/9/11/3316158/graduated-piracy-r...
So yeah, telling people "don't get caught again" works.
