We are operating a company that is very removed from anything that one may commonsensically regard as copyrighted material: we do not stream videos, do not record videos, do not host videos, images or audio files. Our users send only text messages, somewhat like Twitter. We have public user groups. The number of defective DMCA notices has been rapidly increasing in the last 12 months, to the point that we spent multiple hours and signed an engagement letter with a well known San Francisco IP attorney, who called 95% of these notices "bogus", since they do not identify any infringing material. I think Google actually acts on a lot of deficient notices, removing the entire domains from its search, not just the deep links to copyright infringing materials, but the entire domains.
