Don't be ridiculous, how can anyone have evidence that someone doesn't have something? That doesn't mean you have to believe that they do, just because they say so.
These ponzi 'cloud miners' don't even attempt to prove they do actually mine.
Why should they?
There seem to be enough people willing to give them money anyway, who seem to fall into one of two categories:

1) Naive 'investors' who want to believe that they are really mining, despite total lack of evidence and ROI's which defy logic.
2) People who don't care whether they mine or not, just as long as the payments keep coming. (Like your good self).

'Cloud mining' is the perfect Ponzi environment, just make up some numbers and a website, there's no oversight, no proof needed of any legit activity, shrinking payouts are used as reasons to buy more and, of course, no comeback.
Real mining is subject to real costs and of course can't compete with the fairytale stuff on GH/s price.

That's why this "guide" is of no value, it compares apples to oranges.
