Moderation is also why you won’t see comments which are impolite or heretical but may be obviously true. 4chan is moderated, but the goals are just very different from sites that want to avoid the hassle of vigilante activists by enforcing orthodoxy in content. 4chan also goes to some effort to ensure easy identification of its pseudo-anonymous users. It’s also useful fodder to trick people into rage-donating to the right party. Always ask what the business model is for popular web properties. If you can’t figure it out or nobody else can make money in the same domain, then there is probably a side channel being monetized.
