Tomoyuki yes he does boost his rating since he is deleting low rating reviews.
pointing out that his novel is not touching the synopsis for 70 chapters just made him like that I guess. even though he later admitted it was true that he is not touching the powers and revenge theme at least until that chapter.
Also it is a completely different thing if you go and look for his help, while I gave a low review (because of misleading synopsis and tags). I mean it feels like a fan is talking to you if you look for his help, which obviously boosts his ego.
Just searched for his novels and it seems it took a dip (did not find it in top 50 on any category), maybe thats why he is that agressive.
TBH now that I know he is like that even if I were to like his novel I would not pay for it LUL. People have to learn where there is an action there will be a reaction.
