There is no official list of countries that ignore the DMCA but some are more notorious than others for protecting freedom of speech over intellectual property.
Countries that come up often when that subject is discussed in online forums are Russia, Singapore, the Netherlands, Bulgaria, Luxembourg, and Malaysia.
At the end of the day, the service provider is the one that decides to process or ignore a DMCA notice – some hosting providers will claim that they provide offshore “DMCA Ignored Hosting”.
If you find that a service provider in a certain country is ignoring your DMCA takedown request, you could alternatively try to submit a request to Google Or Cyberwebnic so that it at least does not appear in search results.
You may also want to check with a local intellectual property lawyer as the country where the website is hosted may simply have different laws and processes to deal with such a matter.
