NC (AKA tarot) draws a lot of cub art and has included in the description of many of his IB images "Do not reference or repost my art."
as in this artist requests none of his are be redistributed to any site including this one. and any artwork that has been posted has been banned via artist request.
Occasionally there is a parenthesized exception stated like "(Reposts can be made by the commissioner only.)"
In that instance, an uploader ideally should have the same username as the one who commissioned the piece so it is clear that the commissioner is the one reposting.
if you wish to see his art please his official gallery. (account required)
Nobody here but us chickens!
