However, I would be a little bit more carefully to call it already the end.
My impression of his website was that he runs it without help from others and he try to fix it. His support was, especially in the first weeks, quite good. Then he had to argue more and more how he can guarantee 5% a day (which btw he never did). Not every single discussion was fair, I think he gets frustrated to argue over and over again. Then he run into more and more technical problems, including the unavailability of the VPS service over 3 days. The last weeks the website was very often unavailable (login problems etc.). This morning the breaking news about password leaks. If he is giving a one man show and maybe also has to work, all of this could grow over his head, especially with the responsibility of the transferred bitcoins. I can remember how he get angry and complained about a user who was able to payout a small sum of bitcoins he didn't own, because of a mistake on the bitscalper website.
I too am not 100% sure it was a scam. If it was I've lost a couple btc. Maybe his algorithm went haywire, he lost a few hundred btc, panicked and went dark till he could earn them back again...and then this password thing erupted. Who knows. I can see myself behaving the same way, just trying to avoid everyone until I can say, here I am, I fixed it all, sorry. Not the most honest, forthcoming approach surely, but a human one, and a behaviour that doesn't only map to scammers.
I was able to log in again recently, and my coins were still apparently there, and the site let me enter a request to withdraw them all. I'll let you know if they actually get sent out.
