Bitmine have already put up a list of authorised distributors:
http://bitmine.ch/?page_id=5204. If the hardware has been originally acquired from an entity not on that list, it's most likely counterfeit or stolen.
You may assume all you want, but we have yet to see a statement from Innosilicon about this issue whereas bitmine have already made their position quite clear. On the current balance of probabilities it would appear these Chinese machines based on the 28nm CoinCraft A1 are indeed manufactured from stolen tech.
The message you keep quoting was removed which is why I said it raises a number of possibilities. While I appreciate your suspicions bringing to light these allegations, you are unable to conclusively say anything. I've made no assumptions, I just want a clear statement from bitmine regarding this manufacturer. The claims regarding stealing or counterfeiting are as you are no doubt aware very serious allegations and if they do not come forth with these allegations and stick to only non-specific cautions on their site, then I have to give JTminer the benefit of the doubt. So depending on how (and if) they respond, I will be getting the hardware working with an alternative power source and continue down the software path which is all I was originally interested in - or - I will hand the hardware over the AFP.
