Hello I do not know for what purpose you publish on your account other people's work, but it can not be done. I ask you to remove them. Add to Favorites, if you like. That's my job: [link] I know many authors of other works. We have to take action.
I suggest you take down all Illustrations you stole from the online game howrse. In case you don't know, this game is owned by Ubisoft and they have pretty good lawyers... Some of these Illustrations are made by me, and I've already reported them. I'm pretty sure many of the other artists you stole from reported you too. And btw nobody gives a damn about your excuses, it is still wrong to steal from other people...
So, you know that every horse in you gallery is a picture from the Golden Apple on Howrse? You don't have the rights to copy it and submit it to your gallery!
Another countless act of pety theft. Mean it or not it's not okay. Admitting it is not yours is not okay either. Saying "It's not mine and I admit it's not mine" does not make it any less theft. It is against DeviantArts rules to post work from anyone else. You are suppose to post YOUR art only. You're only going to get yourself in more trouble and giving excuses will not help. Just fix it now and its over.
