(Rule 34—“if it exists, there is porn of it”— is so well known that it’s regularly quoted by people who probably can’t name the source or a single other “rule.” Same for Rule 32, “pics or it didn’t happen.”) Rule 30 is “there are no girls on the internet,” and it’s followed by a correlated rule, number 31, “tits or GTFO,” a common refrain from the days in which any internet user claiming to be a woman was demanded to prove it with a photo of her body.
