Didn't Webtoons established a politic of "no-nudes" this last year?
People who had been posting explicit content has had to change of site
I've been posting on Tapas and Smackjeeves this months and noone complained, their politics are more open and as long as your explicit content is part of a story and not a bad excuse
Don't repress your art, it's better to find the addecuate site to post it!
