If someone activates whois guard protection, usually they got "Panama post office box company" address. If you register a domain and use whois protection, probably you will have the same address. It's not mean anything except that hide the name of the owner.
Anyway, good catch these fake team picture. I think this can be moved to scam accusation board.
Also, I see a new trend here. Newbie asking about some service, for which no one has heard. A newly launched website with "great service" there. So, they got some publicity and who knows, maybe he will persuade someone to use them.
Or they're creating backlinks for their exchange, getting it ranked higher in google (although this is probably not the way to do it.)
I've been wondering the same thing. The only way you find "weonix" is by explicitely typing in "weonix.net" into google. There are no articles about them, no google keywords, nothing except now a bitcointalk thread and their domain.
Either OP's friend is getting scammed with something along the lines of the good old "Hey, this exchange offers X amount of money for you to withdraw, but you need to deposit Y $ yourself first" by someone who PM'd him the link of the exchange on a social media such as reddit,
or OP and his friend are the owner of said site.
It's big brain time anyway.
