In its filing to Kiwi regulators, Google reveals just how widely DMCA takedown notices are abused:
In its submission, Google notes that more than half (57%) of the takedown notices it has received under the US Digital Millennium Copyright Act 1998, were sent by business targeting competitors and over one third (37%) of notices were not valid copyright claims.
Wow! I knew there were some crafty SEOs out there, but more than half of all DMCA takedown notices were an attempt to scuttle a rival company? Who knew?
