How to handle plagiarizers

So someone plagiarized my close friend and we want the story taken down, but we have no idea how to get in touch with mibba.

that's the story and the original can be found on 1DFF.com

Plagiarism is a crime, many don't know it, but I study media at Uni and had law, it is possible to sue every plagiarizer, it takes time, but sometimes it's the only opportunity.

I just don't get it, why do peole keep stealing stories instead of writing their own...

@TheKat
This is really upsetting to hear!? Is there a way moderators or admin or someone could be contacted so that something could happen?!?

Even I guess, just some credit would help or something. I know its not the same. I hope your friend gets what she wants in the end, whether its legal based or just moral based.

@TheKat
I'm so sorry about your friend! I think the best way to go if the person won't respond is if you flood the comments section so then when new people go to read it they can see that it's stolen!
Also with getting in touch with mibba I've been told to email contact@mibba.com however I've contacted them before about someone being hacked and I got no response. So try them but I think the moderators have left the site and no longer care!
