draft of this paper, which was entitled Trust But Verify. I would also like to
record my deepest thanks to Shaun Lim for his invaluable help in revising this
paper and updating the statistics with the porting of the Chilling Effects
database onto the Lumen platform. The original material for this paper based
on the Chilling Effects database was first presented at the 15th Year
Retrospective of the Digital Millennium Copyright Act, Santa Clara
University on March 15, 2013. It has since been updated with the dataset from
the Lumen database. I also wish to thank Adam Holland from the Berkman
Klein Centre for Internet & Society, Harvard University, for his kindness in
enabling me unprecedented access to the Lumen database for purposes of this
research. Funding support for the research that made this paper possible is
