We only monitor sites that are known to have piracy. We do not just do general search engine searches looking for your work. This reduces the chances of legitimate sites being sent DMCA Notices. In the cases where a site is known to have a mix of unauthorized and authorized work like YouTube or Scribd, the infringements are flagged for additional visual review by our staff. Unfortunately, no. Some sites, especially torrent sites, are unresponsive to DMCA Notices and utilize hosts who also are unresponsive. However, we do escalate our notifications and after long term notifications, these sites are often forced to lose their domains. With the most accessible types of piracy which are from tubes and cyberlockers, removals are typically around 99% or higher.
