There is a famous sonic Hentai artist that has been drawing content for quite some time. His username is Apostle. There was some information that I have came across that seems to be valuable information and very reasonable indeed. It was uploaded by the user named Luigi on the Rule 34 website.
So how many famous and notable artists will there be that would trace such content? E-Thug was able to alter most of his traced content in order to try and fool others that it's not a trace, but there are features that are still shown.
