We got the same letters, sent to our ISP, instead of us, and we are a legal entity, easy to identify and contact in multiple ways. Legalese is shit, of course, we will stand our ground for sure. Unfortunately, due to procedures by our ISP we might need to temporarily remove a part of the content until the issue is resolved.
