“This is one example where architecture can operate in tandem with moderation. Code is never neutral; it can inhibit and enhance certain kinds of speech over others. Where code fails, moderation has to step in. Sometimes code ought to fail to inhibit speech, because that speech exists in a gray area. (Think: emails in the Gmail system that have not yet received a reputation rating.) But it’s delusional to think that architecture never has any effect on speech whatsoever.”
