It's more the fact that the newfags are the loudest, spamming posts and replying to every tiny little one, patting meme creators on the back and circlejerking, while legit anons have no patience to sift through that shit and work in silcence. No amount of asking politely or messages from mods/BO could change that since newfaggotry isn't removable.
There's this old imageboard tradition of spamming gore to make newfags leave. Lets hope it does not come to that.
