Yes there were, you dumb piece of shit.
You just like blaming their influx on the split because you miss your Touhous and generally like bitching about any possible course of action moot takes here.
Anyone who thinks the split CAUSED these OMG NAROOTOH threads is a colossal faggot. Narutofags have allways, always been on /a/. They stick out in your memory less before the split because they were buried under 30 Touhou image-dumps and Tsukihime fanfuck circle-jerks.
