We knew this would happen. Someone forks it and offers it for free for everyone who pays a small fee like happened to NXT with NEM. This may of course be a scam, but if it's like NEM - well, we don't yet know how well that will succeed. As a rational investor, it only makes sense to be interested.
The peculiar thing now is that this Fake is the best commercial for Bitshares on Bitcointalk. It just became apparent how serious the situation is. I'll start a thread to address this topic immediately.
