Well it's kinda like what people did with that gem game I guess.
We were expecting copies of our website, but not EXACT copies word-for-word. Anything that is successful is copied. This is why we were hesitant to providing too many details of how we EXACTLY do what we do.
There will be many copies of Mining United, some will be legit, some will be scams in the end - it is just how it is. We will not be able to stop copy sites, but can beat them by offering the best service, proven most trusted, first, customer support, etc.
