14.3.1. 4chan/8chan (minimal moderation)# Sites like 4chan and 8chan bill themselves as sites that support free-speech, in the sense that they don’t ban trolling and hateful speech, though they may remove some illegal content, like child pornography. One thing these sites do ban though, is spam. While much of spam is certainly legal, and a form of speech, this speech is restricted on these sites. If the chat boards filled up with spam, the users would find it boring and leave, so for practical reasons, these sites still moderate for spam (though they may allow some uses of ironic spam, copypasta).
I find it interesting that even platforms like 4chan and 8chan, which claim to support “free speech,” still engage in selective moderation. The fact that they ban spam shows that no platform can operate without some form of content control. If spam were allowed without restriction, the site would become unusable and users would leave. This suggests that even so-called minimal moderation platforms must make practical decisions about what kinds of speech are acceptable.
