The "illegal" rule requires a lot of clarification. The interpretation here seems to be "It's against our policy to post about engaging in illegal activities", or maybe "it's against our policy to advocate illegal activities".

Services based in the US are not legally obligated to prevent users from writing about using cocaine, or pictures of white powders they're claiming are cocaine, or writing that it's desirable to use cocaine, so the post itself is not illegal. Real policies for content moderators should be much more detailed than what's in this game so that most moderators will reach the same conclusions about whether a post violates the policy.
