Vaush did not in fact have any loli porn. One (some?) of the art he downloaded happened to be drawn by somebody who for some reason chose not to draw lolicon that day and Vaush innocently thought it looked hot. As somebody who spends way too much time on pixiv it's happened to me enough I've made a habit of thoroughly checking an artists profile cause some really freaky people love drawing normal stuff every once in awhile. It's quite off-putting.
What we should really be talking about is the obvious AI art he had downloaded like a absolute troglodyte (and the horse stuff has been known for years but it's still funny)
