Tier 3: The lowest. This is for wikis like The Roblox Creepypasta Wiki and The Creepypasta Fanon wiki. Basically, they allow anything, and I am pretty sure that no pastas get "deleted" per se. (I even remember seeing a very full deletion log on the RCW!)

Tier 2: The middle. This is for pasta wikis like the Minecraft Creepypasta wiki, the spinpasta wiki (not counting THX Tex, that's for the Creepypasta fanon wiki), the lost episode creepypasta wiki, and the someordinarygamers wiki. These wikis are more popular, and they also have popular pastas on them, albeit not popular enough to be on the Tier 1 wikis.

Tier 1: The top. This is for the main creepypasta wiki. It's basically the main source/real deal for spooky internet stories. It is also where some other pasta wikis get their pastas from.

(Extra wikis: The trollpasta wiki, if you want something to laugh at, and the creepypasta land wiki which is basically a tier 2 creepypasta wiki)

(This is my personal opinion BTW)
