Thanks for letting me know! I probably won't do anything about it though, since this happens semi frequently...which is why I watermark things hehe. But it's alright, so long as they are not outright claiming they drew it themselves. Thank you so much though, I always appreciate when people give me a heads up about these kinds of things.
That person removed the watermark of my friend's pic so she is sort of indirectly claiming the art as hers. I've made countless reports to Tumblr but they can't do anything about it since the art doesn't belong to me and only the artist can make a complaint.
She doesn't give credit to all the artwork she features on her blog. Even when the artistes themselves already have their own tumblr link for people to like and reblog, this person just takes the art and posts it as a new post which is wrong. =/
