I like how there's really no easy solution for this one lol, he did take it to publishers, it isn't just anonymous trolls hating on him but his real life friends, there's no out for Smart-tarou... I'm sure in his career, FKMT has befriended some equally hopeless mangaka. Maybe this is partially a message to them...
