I only checked whether content was already uploaded to e-hentai, I did not think to check if they sell content elsewhere outside of DLSite. So in case of TengaWa, because I got it from DLSite, it's censored. But if I got it through Patreon, it would not be.
However, a Patreon subscription would cost $11 and this product was 40 Yen so, there is that..
Well I search for every creator before I upload (or even buy) and didn't come up. Why use different handle on DLSite and Patreon makes no sense to me. Guess you could expunge this unless you consider 2 WEBP images worthy of a duplicate. Hardly is.
