There is a kind of shitposting warfare going on right now between the trifecta of shitposting: /3dsgen/ - /vitagen/ - /jrpgen/. This is likely because some of the users overlap. As far as I know there is also a (or multiple) IRC channel where certain people group up to organize spam raids and false-flag in /vitagen/ to talk about how the Vita is shit or dying, in general just posting vitriolic comments to get reactions.
3DS general is very, very slow so when a thread dies no one bothers making a new. They prefer invading /vitagen/ and flame Vita users. I had to make a new thread 3 days ago so they would leave /vitagen/, which is still up right now with only 450 replies.
JRPG is being flooded by spam and some user they call Kattfag who only posts Katt pictures or spams his "review" of Breath of Fire, see >>3959.
