The group which includes Paul Vixie, Dan Kaminsky, Steve Crocker, David Dagon and Danny McPherson, have detailed several serious technical and security concerns in the event that the mandated DNS filtering is enacted into law. Dan Kaminsky says: 'There are efforts afoot to manipulate the DNS on a remarkably large scale. The American PROTECT IP act contains several reasonable and well targeted remedies to copyright infringement. One of these remedies, however, is to leverage the millions of recursive DNS servers that act as accelerators for Internet traffic, and convert them into censors for domain names in an effort to block content.'"
