I am the earlier adopter signup for the 5 Gigahash/s - Indefinite Contract (July 2013), no sign of mining and no reply, no answer and no announcement from them. So is it a scam? or is it? or it is.

there was a newsletter they sent. you didnt receive it? mining has started, but only at 10% capacity due to their asic suppliers not delivering. so this is what we get at the moment.
since they are a start up, i suggest for us to be patient, but that doesnt mean we should stay quiet.

WE will be at 1.3 Terahash as of this Thursday (8th August). As promised, the longer BFL delay, the more we will act by making emergency purchases to get you closer to 100% capacity.
We are currently on Bitminter at 840 Terahash.

Thanks for your patience and understanding.
I sent two "tickets" via dashboard (though it doesn't seems to do much as dashboard) and it got deleted in 24 hours, is it how you guys handle enquiries? Beside, since you guys did such a great job designing such a fancy website to attract orders, it won't hurt to develop a simple and functional "dashboard" which as a client, able to view latest announcement, mining status, news etc. I'm a not a frequent visitors to bitcointalk hence would be able to read the announcements here. Yes, you mining somewhere and offer an upgrade, BUT we don't know, that makes me feel uneasy. I believe I'm not asking too much.
