A friend of mine on DeviantArt who does the most amazing Despicable Me fanart has been having rotten problems for a long time now. She has been having someone steal her work and use them both on DA and on Facebook. All please to remove the pics have come to naught and so me and a few friends have attempted to raise awareness of this and Nick set up some Facebook things. one is a cause, the other a page.
The Offending Facebook Page (CLICK)
This person uses roleplaying to cover up her guilt and instead of replying properly to your requests, she will pretend to be Edith from Despicable Me. It's getting silly now.
Her DeviantArt gallery has a ton of stuff by other people, just recoloured. And the images she used don't have the share license on it.
This is the art thief (DA Account): http://kjhrex.deviantart.com/
And this is her Facebook: http://www.facebook.com/krysti.henton
And here's a nice image for you to facepalm at.
