It's true. Type in your username and deviantART next to it and you will find that even the images that you LITERALLY disabled to "Members Only" and "NO sharing/downloading"(like mine that I Always Do + Watermark), you'll still find your art on there which can get stolen. So I'd recommend you to pass this around and sign it too or something to stop such thievery.
In other news, anybody remember this old journal entry of another
art-theft website?: ancientechidna.deviantart.com/…
They would SELL YOUR ART AND MAKE PROFIT FOR THEMSELVES.
Now, I'm not sure if that website is still active or doing anything about our own art, but I suggest to also keep an eye out on your art there.
