Regarding this particular example:
I saw this website and couldn't believe that it was genuine: [URL redacted]
That's pretty blatant spam.
Regarding “is this download site genuine” in general, I don't see how it fits our scope. The closest way I can think of to make it match is that it's asking for recommendations of a download website, which is off-topic. And even that is a stretch, it's more of a “rate this website”.
Regarding “is this application ‘legit’?” (as in does it do what's advertised, is it not malware), that would fall under Can I ask if a particular software will fit my needs?, for which our policy is to change the question to ask about said needs and include a suggestion about which not enough is known to make an answer. If the question doesn't explain the asker's needs, it isn't suitable.
