gollark: Yes, it's called SCP-682.
gollark: Some of them are just weird for reasons other than that, though.
gollark: 4703 somehow *does things* just because the law says it can, even though the law is just a human concept and only affects what humans do.
gollark: Really, one of the main things which makes (some) SCPs weird is that they take convenient abstractions/concepts and turn them into immutable physical laws, while our real universe just runs on... well, physics. 173 is affected by line of sight, even though this is just a thing humans do to reason about... looking at things. 005 is just a magic item which unlocks things, 048 is just a label we assign to things which somehow affects them.
gollark: Alternatively, the machine breaks, if it prefers simple changes - so I guess make it STUPIDLY redundant.
