I’m not at all fluent in legalese but I couldn’t find anything in their ToS that explicitly stated something like that. The skeeviest thing I could find in it was this:
Let me know if I missed something tho because I don’t like using that dinosaur of a website much to begin with. I could go on a long tangent on why I think it sucks ass but for now I’ll just say that I maintain it out of some (likely misguided) sense of loyalty. It’s the place where I started out with art and I still have a handful of followers on there that were around from the beginning.
Since apparently this comes up every time someone actually reads an art website’s ToS, that particular clause basically allows them to generate thumbnails, slap the DA watermark on it, potentially incorporate it into an advertising banner/slideshow, that kind of thing. It’s a giant cover my ass for trying to sue Deviantart because someone stole your stuff off of it. And like most legalese, it’s basically boilerplate to cover as many bases as possible.
