As an artist myself, who has been at this for many years, I know when someone is using a base, and when someone is drawing themselves. You are not the first to use that base, and claim not to have, and you will not be the last.
You see, if you had never seen it or used it, it would be awfully strange for the spankee's body to line up so precisely, and the spanker's hand as well. In addition, I did no resizing to make that work. The images are precisely the same size. You used a base.
I'm sorry that it's upsetting you, but my decision remains the same. Whether you continue to post or not is up to you.
