If you followed the Copyright Office request for public comments on the DMCA “notice and takedown” safe harbors, you will probably be aware of reports that a group called Fight for the Future generated 86,000 comments to the Copyright Office in approximately 36 hours. I will give even money that it will turn out that investigation will reveal that most of those comments were fake.
One reason I’d make that bet is because they look fake. Many were anonymous or pseudonymous and there’s really no way to know who or what submitted those comments. And that’s why there’s a question about whether this kind of public comments can be used at all for policy making.
