Sometimes I want to cry when I place worldbuilding guidelines that state no humanoid/furry aliens (and god no to space elves), no pop culture and no space-whatevernation I like. And than someone does all the above anyways. I am not trying to be completely obstructive with guidelines either, my belief is that with a list of NOs and a good set of environments with a decent set-up scenario you open creative thinking more than just giving someone a box you can do anything you want in. Maybe I just have bad luck with who gets interest in my stuff.
