When you go to someone's house, do you shit on their floor if there isn't a cross stitch hanging by the door that says "Please don't shit on our floor."

We shouldn't need rules, because everyone here is an adult and the expectation is they will conduct themselves as such.

Beyond that it says right on the tin, "Star Trek memes and shitposts," so if it's not Star Trek related (and the bar for that is incredibly low) or it's not a meme or shitpost, then there's no reason for it to be here.
