Poe's Law

Poe's law is an adage of internet culture holding that, without a clear signal of the author's intent, a parody of an extreme view is indistinguishable from a sincere expression of it, and vice versa. Originating in a 2005 forum discussion about creationism, it has been generalised to mean that any sufficiently earnest-looking satire of extremism will be mistaken by some readers for the real thing.

Poe's law matters greatly for content moderation. On a platform like Reddit, moderators and automated systems must constantly judge whether a post is a genuine call to a harmful position or a joke at its expense, and Poe's law warns that this judgement is often impossible from the text alone. The same ambiguity is exploited deliberately: bad actors hide real hate or extremism behind a claim of "just joking," daring moderators to overreact. The principle underpins why irony, satire and dog-whistling are such persistent headaches for platform policy and why context, not just wording, drives enforcement decisions.
