[The DMCA] creates a safe harbor for
online service providers (OSPs, including
ISPs) against copyright liability if
they promptly block access if they receive a
notification from a copyright holder or
their agent.
This means that if you contact the online
service provider, including search engines, they
are compelled to work for you to stop the
copyright infringement and violation.
According to
Google’s DMCA statement:
It is our policy to respond to notices of
alleged infringement that comply with the
Digital Millennium Copyright Act and other
applicable intellectual property laws, which
may include removing or disabling access to
material claimed to be the subject of
infringing activity. If we remove or disable
access to comply with the Digital Millennium
Copyright Act, we will make a good-faith
attempt to contact the owner or
administrator of each affected site so that
they may make a counter notification
pursuant to sections 512(g)(2) and (3) of
that Act.
