I took out the entire "Main Game" folder. It consisted of entries that were an Adult Fear that didn't seem to scare anybody, Fridge Horror, a hypothetical, or disturbing imagery (Nausea Fuel, etc.). Those aren't Nightmare Fuel. You can see the clean-up discussion thread here.
I've added the entries from the Main Game folder back in because their absence makes the page look incomplete. I don't see the reasoning for their removal, especially since they are not far off from the content in DL Cs that have been kept in for some reason. Given how the page is made up entirely of subjective opinions, it doesn't matter if you don't personally find it scary. Because of that, your statement that the examples on the page "didn't seem to scare anybody" is a nebulous claim at best and complete nonsense at worst. Additionally, you seem to think Nightmare Fuel is mutually exclusive to other tropes. Some things can provoke both nausea and feelings of terror.
