This is what I replied to you, and many others all over their account probably a few people multiple times, but I can't remember every name I reply to.
"RealRavenRavenRaven" here on Deviantart isn't the real artist of, probably most if not all of the posted artwork. Kinda weird they'd need to put "real" in their account name, but anyway they're just stealing the artwork and posting it as if it was their own.
Most any art you can find on that Tumblr was posted here probably days later. This Deviant isn't the account listed by the Tumblr account, as it's Deviantart account. That Tumblr account which posts any artwork here days earlier that it does, I assume all the proof I'd need that this is an art theif.
Thank you for pointing it out... I already figured it out later... she blocked me when I called her out on it... I can understand being a fan of someone's art and posting it to your profile... but not to the point of claiming ownership. -,- It just makes the original creators not want to bother creating anymore of their work. Something this thief doesn't get obviously. -.- Thanks for spreading the word though about her. :3
