So she does have an LJ after all.
Let's just all hope that this was an isolated incident...
But either way she makes no mention in her journal about winning the contest, which is also a little strange to me. I mean I made the point of announcing I had won even if I got 2nd place. It's a small contest and everything, but as 1st place winner she still would have gotten 35 $ worth of anime and a free T-shirt with her design on it.
I am glad someone caught her before it was too late, cause I know it would have sucked for Z-con should they have used the image to make t-shirts sold them, and then found out it was actually Dead Rabbit's work.
