And what do you do when you go through all of that time and effort (and potential expense) and get the very likely outcome that the claimant is not in your home jurisdiction?
You might have trouble getting the opponent to cooperate but if your ultimate goal is to get YouTube to do something then that could work just fine.
Again, clearly legal action isn’t easy but people seem too inclined to throw up their hands instantly.
Learning how to take basic legal action is just a core part of running a business, and someone earning from YouTube at this level is indeed doing just that.
My (and the GPs) question was: let's say, following the filing of the requisite legal documents and the accompanying fees if any, you receive the contact information of the claimant from YouTube. You are in Germany. The claimant's address is in Turkmenistan. What are you meant to do next?
