Ensuring that there's no useful data in your logs...
As I wrote about earlier, TorrentSpy, a file-sharing search engine, was ordered by a U.S. magistrate to enable logging on its servers and to subsequently make those logs available to the MPAA, the plaintiff in an illegal file-sharing lawsuit against TorrentSpy. They have lost their appeals and as a result have decided to block US IP addresses from their web servers (which will effectively ensure that no information interesting to the MPAA will reach their logs). This ruling also puts copyright law squarely at odds with privacy rights, as pointed out by the Electronic Frontier Foundation. The whole case seems to hinge on the fact that the judge interpreted the fact that information such as IP addresses temporarily reside in a computer's RAM as meaning that information is "stored" by the computer and therefore discoverable; many computer experts reject that argument. More analysis of the implications of the ruling are found here.
