The Multatuli Project: ISP Notice & take down
by Ragnar Schierholz
Member of the Bits of Freedom group conducted a test to seee/prove how easy it is to take an arbitrary website down.
They put up a website, published a public-domain article dating back to 1869/1871 and clearly stated the age and public availability of the document on the site. Then they notified ISPs about illegal content being published and asked for a takedown of the site. The requests were sent from an anonymous hotmail email address in the name of a non-existent society claiming to be the copyright holder. Most of the ISPs did take down the site. Check a brief presentation of the results or the full report.
So where does that leave us? I guess there is both an insufficient legal regulation (or at least it's insufficiently transparent) as well as an insufficient sense of responsibility on the ISPs side.
