how do i report someone?

1. ok so I was scrolling through the stories looking for something to read and I found one of my stories that someone else is trying to pass off as theirs. I can prove this because the full story is on my account along with the sequel and they only have a few chapters up. Also my first has been finished for quite some time so you can see that mine was written first. Is there anyway that I can report them or have them take down the story? Its really bothering me that someone is taking credit for my work.

Hey I'm not sure if you sorted this out yet, but just on the off chance you haven't, I read this yesterday and thought it would be helpful in case this ever happens to anybody else as this isn't the first time I've seen this problem on this site before. This is from a tutorial posted on Mibba by dru is beautiful. The tutorial is called 'Someone stole your story. Now what?' (Can be found here)

'On Mibba, you would get a link to both works and message an administrator to let them know what happened. The administrator would look at the dates and compare the stories for plagiarism. They would then remove the plagiarized work and the user would be permanently banned from Mibba, as per the Site Rules. This is also how you would handle plagiarism on one of our sister fandom sites.'

They also explain what to do if you find your stuff plagiarised on other sites. I'm have no idea who the administrator on this site is, but contact the admin on Mibba and they can help.
