Remember how I’ve been trying to pass variants on Issuing NPC Pronoun Permits for a while, to restrict or eliminate the pronoun replacement clause in “Spelling and formatting”? My actual motivation was to stop an extremely broad gamebreaking scam.

“E” is a spivak pronoun. It also happens to be a recurring feature of other words. So if I wanted, I could turn, say, “introspection” into “introsptheyction” to yank the rug out from under anyone memeing in level 3. Or, recursively, “introspththththeyyyyction” to make the point that it’s deliberate mutilation and not a typo that can be corrected using the same rule. Obviously, this breaks the game rather thoroughly when applied to general ruletext rather than quoted flavortext. I therefore didn’t want to reveal the full reason for the fix until after it was fixed, though I eventually passed it by disclosing a watered-down version.
