He never admitted it publicly, and keeps half-hiding behind claims of 'size difference' and 'sexual dimorphism', if he even tries to justify why he's drawing tiny flat girl being boned by guys 2x their size, and not just gets angry and insulting. Everyone just seems to go 'well the artist doesn't say it's cub so if I jack off to it you can't say I'm a pedo!'
Be careful, the thread is absolutely full of Zaush's "not cub" content. And also tons of cub porn where he isn't even bothering to hide his personal desires.
