User NobelWolfen is uploading others art without credit it seams....example: Goldenwolf's art Though it doesn't look like any attempt to remove signatures were made, so it may not be an issue for some.

There are many other artists on there as well, and various photographs from sites. I do not know them all, but you may just want to check to see if your stuff is there. I haven't contacted the person. I will leave that to the artists themselves.

Just a heads up.
