I normally wouldn't bother responding to one of these types of posts, but either you or someone else keeps posting this list and I'm going to go over why MOST of it is completely bullshit:
I think those dismissing this as not a scam from the fact they put on a semi functional demo are overlooking a few things:
1) They have yet to ship any boards
Many companies pre-announce products. This has absolutely no bearing as to whether or not something is a scam. If it were, most tech companies would be scammers. This point is invalid.
2) Their numbers do not match their claims
You could easily argue with equal weight that his is evidence that it is NOT a scam. Since if it were a scam, why not show something that has the actual numbers? This point is invalid.
3) They claim to be incorporated but have not provided a business license
Completely immaterial as to whether or not they are scamming. See next point, which is basically a rehash of this point.
4) Since they are not legally incorporated and they claim to be they are an illegal organization
While they may or may not be an illegal "company" this also has absolutely no bearing as to whether or not they are scamming. They can be operating an illegal "corporation" and still provide a viable product. Conversely, a scamming company can be operating a perfectly legitimate company and still scam people without shipping any product (eBay et al does this all the time). So, that being the case, both points 3 and 4 are completely invalid.
5) They could have just made up a couple boards they thought would get the numbers they claimed (and failed) to try and show they werent scammers
Possibly the only semi-legitimate gripe. However, I offer you Occams Razor as a rebuttal. Why go through all this trouble to produce actual working product (if not at the target estimates) to scam people when they could provide mock up fake hardware to look even more legitimate and scam people with far less effort, time and money?
6) They keep on bouncing between Bitforce Labs and Butterfly Labs as a name (seems odd)
I've not seen this, but I'll take your word for this that it's happened. Assuming it has, so what? How is this, once again, evidence of a scam?
7) Their so called business address is actually residential
Yet ANOTHER straw man. I have in the past and currently run my corporation from a residence. I have been in business for over 10 years. So what?
Even if they are "legit" they could still go bankrupt and no one gets anything
So could any company. So could any start up. So what? Another invalid point.
9) As mentioned in the previous post by someone else the power numbers are way off - the whole benefit of fpga boards
Rehash of point number 2. Already demonstrated to be an invalid point.
10) If they can produce the boards with the numbers claimed they can just run off with the boards, close shop and not ship anything (Paypal buyer protection is a joke and wont protect you from this)
And this is different from literally EVERYONE ELSE that sells something online, how exactly? Invalid point.
11) With a $26k box for preorder they have a lot more incentive to keep people believing that they are legit in the hopes to get some orders (big money) for this
This is effectively a rehash of point 5 in a frilly dress... that said, Occams Razor applies.
It is still way too early to say this isnt a scam. I have been fooled by more elaborate scammers before.
Really? That must have been an epic scam, then. In either case, if it does end up being a scam, it truly will be epic. However, I think far more likely that if it ends up being a complete bag of fail, it would be through over-reaching design and over-promising product and not through any intentional attempt to scam.
So you have one semi-valid point which can be fairly convincingly dismissed by applying Occams Razor. Now there may be other reasons to think it's a scam, but there's nothing from this list that is even remotely valid.
