Difficulty names must indicate the difficulty of the map, and if it's a guest mapper, show that mapper's name. This is to help players find out what kind of difficulty it is without having to start the map first, since the star rating isn't always accurate. Things like [Insane], [Expert], [Pro] or [Level 5] are acceptable difficulty names, [Tree] isn't.Because a rule like this seems necessary. If difficulty names aren't supposed to indicate the map's difficulty, what are they there for? To give the mapper creative space? I'm by no means against creative space, but this doesn't belong into the difficulty names. Post all the creativity you have in your map posts, for what I care.
