If you’re referring to .ml, Rule 1 is saying anything they don’t like (criticizing an authoritarian regime, etc)
It’s a bit more complicated than that. Basically they distort every single rule, not just rule #1. Rule #1 is specially common because they label criticism against certain governments as xenophobia, but sometimes you get “rule #4” (because you insisted on a certain point) or “rule #2” (because someone said some stupid shit and you didn’t play along).
