Nah. SaiGAR, while it was a terrible idea, is not the one to be blamed. The problem are the newfags that don't lurk AND at the same time comment on their forums about 4chan. That and chanology.
I don't browse forums anymore, but the last time I entered to one to check one of my oldest accounts I found that the whole place was full of KAWAII DESU NE retards spamming memes , and inviting everyone to come to /a/ because it was so "cool and hardcore".
