I haven't bought into their cloud mining services, but I do use their faucet. Haven't gotten to the minimum yet, but I noticed they cut the number of ads per day. When I emailed them asking why they just denied their was a problem.
Here were my emails with them (bottom to top is the order recieved):

Starting a quick IRC would be good because it would keep people knowing that it isnt a scam by talking to each other... unless it is a scam...
Them:

Me:

Me:
How are us members able to know that you are legit? at the moment, it seems like you may not be, with all of the Bitcointalk threads being locked. The "proof of payment" page could just be you sending stuff to yourselves... Can you find a way to prove that you are legit?
