I dont think so sir. I mean, I don't get it.
If us "normal" anime-fans and you nighttime-elite-weeaboos would just peacefully coexist an these boards, 4chan would only become better.
more content, more opinions and more user will improve 4chan regardless of what time it is and both the daytime- and the nighttime-communities can only profit from working and communicating together.
look at how much both 4chan and gaia improved with the influence of each other. and it's the same thing here.
