Without presenting any evidence, your comment sounds like pure prejudice. The site has its few problems:

  - 2 advertisements and
  - link to facebook.

Besides that it is:

one of listed filters in creative commons search: https://search.creativecommons.org/search?q=trust&license=cc... ,

does not insist to became a member,

has no paid premium features,

very clean,

no sketchy ads,

no intrusive popups,

default presentation is not the most "clicked items",

and has no links to any suspect site.

I can't really see why it looks "'not legit at all', and would probably want to run it in a sandbox before downloading any links".
