I've often wondered about this...
With iichan, it wasn't that much of a problem since the user number was pretty low anyways, and as stupid people ratio tends to grow exponentionally, there were considerable less than at 4chan.
I don't know how many users / visitors 2chan has, but I doubt it's less than 4chan. So naturally they must have a huge number of idiots there, too. Or does the japanese society lack them? I doubt it.
So, how does 2chan moderate itself? Do they have many moderators or just a few. I have seen them expose the offenders IPs together with their threads sometimes, dunno how that is supposed to help, really, but yeah.
Maybe my perception about the whole thing is skewed to begin with and 2chan has as many trolls as 4chan (the many off-topic posts, most notably of real life penor in /7/ are an indication of this) but somehow I have the impression that 2chan has a much more functioning "community" than 4chan ever had.
Incoherent ramblings. Contribute anyways!
>Do they have many moderators or just a few.
Misato said it best in Evangelion: The Japanese take care of the needs of others before their own. And since Sociology has taught us that anecdotal common sense applies both to entire societies and single individuals in all situations, this is the answer (the penis posts are signs of our futaba idols detecting their fellow users' need of cock as a result of their above mentioned instinctual behaviours).
Well, it's pretty obvious they don't care about off-topic posts as much as we do over here. The IP revealing seems to be for more illegal activities. Maybe it's meant to scare people because it makes it easier to track them down.
