You can ignore the words of nurdy trolls.
aimasu should belong to game category, because it is for video game.
idolmaster should belong to comic and anime category, because it is for animation works.
(you can see Idolmaster both game and animation)
But nurdy trolls want to murge 2 boards with their egoistic will.
They did meaningless vote, but it has no pursuasion to abolish bbs aimasu.
They dont't know it changes themselves Idlemaster, not Idolmaster.
