How does one report stolen content on this site?

Hello there,

I'm rather new here and more of a background-type of person who, well, sticks more behind the shadows, so to say.

Either way, though, shortly after my account formation, I discovered a story of which I know and have proof of that it's as good as 1:1 copy done by a different author on Fictionmania and them and the poster here not being the same person, effectively rendering the BigCloset edition a post of a stolen content without the original author's consent.

Unfortunately, either through my rather green-horn tendencies on this site or just so, I find no means of reporting same story or its 'creator' of such, hence leading me to the question here how one can ultimately do so, in the end...?
