A common mistake by most people, not trying to rub your nose in it, is to assume because it's not .com, .net, or .org that it's somehow "offshore".

.info's registry is Afilias, a US based company. Your domain registrar, Namecheap, puts in the order from Afilias. All it takes is somebody to complain to Namecheap or Afilias as I looked up your domain on Google then you said that you were offering adult content. There are companies, such as MediaSentry, who handle DMCA complaints and shutting down websites content producers find objectionable such as download sites or video sites.

If you are looking for protection, find a domain extension that is overseas and look up who the registry is. After you verify that indeed the registry is offshore, find a domain registrar in that same country or offshore to register the domain for you which protects you from your domain being seized or shutdown. This would leave your hosting vulnerable and most websites jump from provider to provider, so I'm going to leave you securing your own hosting to you as I gave you the most important answer to your problem.

Good luck
