Ok then answer these simple basic questions:
1. Show the bitcoin address that you are mining to so we can verify you have actual mining hardware running.

Good Point, This seems like a scam.
I must say though, I'm sure to run a service they don't have to register a business, even if they were legit or not..
Technically they don't have to do any of these things, AND still could be legit. However for a legit service it wouldn't make any sense to NOT provide each and every possible proof of that legitimacy. In other words, the duck test: why would a legitimate service walk and quack like a scam?
