You've probably seen a few artist journals about this already.
This individual takes furry art and removes the signatures before posting the images to their Instagram and other places. That's really, really fucked.
Their Instagram has been set to private as of this morning. It contained ~5000 images that had been stolen from many, many artists in the fandom. I have no idea why the hell Instagram hasn't taken his account down yet.
