A client of mine received a DMCA claim from IFPI on a blog post he wrote 12 years ago. IFPI sought removal a Creative Commons licensed song that was featured in WIRED magazine. The website host (Harvard) took the content down, despite the fact that the material in question was clearly lawful. This reflects both IFPI's questionable takedown tactics, and the failure of the DMCA to provide sufficient disincentives for such bad behavior.
Here's our response.
