Just because an artist is inactive for whatever reason does not mean their creations or content are free for you to use without their permission. Please ALWAYS ASK THE CREATOR, instead of assuming you can just do that. Most of us are just too busy to post things and do not appreciate having our creations taken or used without our consent.
I do not want any of my art, characters or canon (or ANY content) being reposted or used without my direct permission being granted first. If I didn’t put it there myself, it doesn’t belong there. Please respect that.
