That kinda proves my point: a normal "officially registered company" would put their office address on their website. A name in a PDF in a random country doesn't inspire confidence and makes me think this is at best a postbox company.
Offshore companies have always only served to represent the legality of a business, and that's a great way to increase credibility. Earlier, I did a little analysis of that "PDF register", mostly shell companies, so I understand that there is no insistence on publishing information on the site, because it is not representative.
