We have never had to sue anyone. When takedown notices are ignored, we just file it with whoever is hosting it. They then tell their client to remove the content or else be shut down.

Here are some older notes about it:

approving service by email

The Court made a rather ominous note:"We note that the Default Defendants are commercial enterprises and persons involved in the distribution of adult Internet content." So, if you are a pornographer the Court may limit your rights

The decision would possibly be very narrowly interpreted to foreign litigants and is only precedential in the 9th US District.

I would go the administrative routes first with ICANN (false filing information complaints) and the ISP (Hosts) and Registrars {copyright infringement issues} first. Having to take a case into appeal in the US Courts is something you would be very lucky to succeed in pro se.
