Also, I may be speaking purley from my experiances at the Friendship is Magic Wikia, but if that's anything to go by, most Bronies either don't care about, or show dissdain for 4chan's influance - one Brony, who was trying to get a character's name changed, and one the points she/he made in his/her favor was that she was named on 4chan (my side of the argument was hardly anyone remembered that, and the name had been so widley used, including by someone who works on the show it didn't matter). So yeah, 4chan has barely eny influance on Bronies these days, if it ever did (which I seriously doubt).
