If you've been following the discord, he's been posting over several months saying that it's because he gets burned out from drawing too much. He's an artist for a day job, then does futa in his off time and that his career is just more important at the moment.
Not only that, he mentioned multiple times that one mistake could send him to prison due to his country laws on shota. Australia has a no tolerance law on even fictional shota and you're throwing into the sex offenders list right next to actual pedophiles.
He even explicitly mentioned that he enjoys drawing futa as a hobby, but shit just kept piling up and just couldn't keep up anymore.
