To clarify, on which part of their site said that Bitcoin and visa endorsed them? Far as I can find about those names were on the footer of their site,
which rather looks like a statement that they accepted payment from these "providers" rather than being endorsed by them.
Granted, the site has several red flags, and it's rather foolish to take them seriously. I mean... they don't even list their address, and their "about" page is very... worrying. But there were not any statement that visa and other providers endorsed them. At least none that I can find of.
