Greetings, I wanted to share with you this document, prepared by well known DNS experts for the US Senate. It explains in plain words why filtering DNS queries is technically problematic. Although this was written as a reaction to a US law proposal, its contents are relevant well outside the US context. If you do not wish to read the document in full, read the executive summary and the conclusions, which I have appended below: "as discussed in this paper, the mandated DNS filtering provisions found in the PROTECT IP Act raise very serious security and technical concerns. We believe that the goals of PROTECT IP can be accomplished without reducing DNS security and stability, through strategies such as better international cooperation on prosecutions and the other remedies contained in PROTECT IP other than DNS-related provisions. We urge Congress to reject the DNS filtering portions of the Act."

This is not an ICANN effort, though ICANN people have helped a lot. Sharing with you for info. Feel free to share further.
