I was just referring in terms of cloud-mining in particular. Would you want to see the all the miners at work ?
hashcoins.com ~1+2+3+4+7 => 5/7 = (very) suspicious (user selectable pool requires fee, dc pictures show no miners, linkedin profile doctored, hardware sales very dubious,..)
2 miners doesn't cut it, any kid in their mothers basement can have that. To remove number 3 above they need to have a least a few pictures of the datacenter with rows of miners or a video walk through of showing their complete capacity.
