Yesterday I received a lot of messages on my deviantart page, congratulating me for “winning” a 2NE1 fanart contest. Since I never submitted this to any kind of contest, took me sometime to understand what was going on.
After some research I found out that someone won this fanart contest posting my work but after cropped my signature off from the original piece.
-Here’s my original artwork, posted in 2011 on Deviantart: http://adrianamelo.deviantart.com/gallery/#/d48tcz3
-The one he submitted to the contest:http://yfrog.com/0t04szj
That person keep saying he didn’t stole anything, but he never contact me previously about the artwork, never mentioned it belonged to someone else and even accepted compliments towards the drawing. Once again, I ask you to compare what he subbimted and the original piece. The fact that the signature was cropped out is reason enough to show his real intentions.
I have extreme mixed feelings right now, because I LOVE 2NE1 and is great to see them holding my drawing, but really SUCKS it was credited to someone else. TT-TT

I would really appreciate if this post was reblogged and the news about the art theft get spread. :/
Thanks(and sorry for the EngRish)"
UPDATED:
@GlobalBlackjack has deleted the contest winner tweet but has not taken any further action for the original artist or against the fraudulent douchebag.
Douchebag took to their twitter to defend themselves, failing horribly:
Think Omona can help out? Tweet @GlobalBlackjack in hopes that the issue may come to light.

Date: 2012-07-15 08:09 pm (UTC)From what I can see this person only cropped the picture. SMH. You'd think they would have put in more effort at least since the contest is such a public thing. Well you're caught.
Hope they give the credit to the person who deserves it asap.
BTW: That's a really good drawing.

Date: 2012-07-15 09:19 pm (UTC)But to be honest, isn't the way they held the contest kinda careless and rather stupid? People posted their fan art on twitter so it isn't surprise if the art work was stolen, or if someone else also stole another art work? I mean, aren't they supposed to send in THE original piece to YGE?? And sing it?? That's how the contests are held where I am coming from, even if they had to travel overseas.
I honestly hope YGE will do something about this asap.

Date: 2012-07-16 05:14 pm (UTC)And idk if English isn't his first language or something (since he can barely bring his point across but he does tweet in English) but the amount of "your" "you're" mix ups makes me want to unlock my account to tweet him
