I read this post recently where the domain owner filed DMCA take downs against a domain however the domain Google approved the DMCA takedown against is still out ranking the domain they stole from.Is the penalty Google hands out to bad domains only short term like a 1 month penalty?
Does Google Penalize Domains After DMCA's Approval

Sites with high numbers of removal notices may appear lower in our results. https://search.googleblog.com/2012/08/an-update-to-our-search-algorithms.html
