Post making contest 6.0

Rule 4 doesn't seem to be caused by time of day (two identical posts in the same minute don't proc it, IIRC) and there's no feasible way their post numbers are related. The only other context-related thing I can think of that would make identical posts succeed at different points is how they link up to posts above/below them, but identical sequences of posts also will randomly not pass rule 4.

I'm very confused.

You're forgetting about cycles.

For instance, someone could have a rule that's effectively "post must have the letter A" when the round starts, then with each subsequent post it becomes "post must have the letter B", "post must have the letter C", etc.

Or the rule could change when it's passed, or with every new page of the thread, or something. We've also had rules that involved the username of the person posting before you.

Also, to be more clear about what I was saying earlier, the game is DROD, not DMoD.
