So it was brought to my attention by another user that an "artist" on Deviant Art by the handle salvador-lol has been posting work on his DA Page done by other artists with the signatures obliterated or otherwise obscured.
I urge anyone who can contact the original copyright holders of the work he has posted there to do so and inform them of the theft. Since DA Only accepts DMCA claims from first party (even if proof of theft is hosted on their own site) copyright holders this is the only way to get this theft stopped. I have contacted a few of the artists about this, but I believe the more people who put the information out, the more likely there is to be a response.
