The more I think of it, the more surprised I am that I can't remember anyone trying this scam. We've had plenty of attempted hardcodings of players into rules/proposals (e.g. "G. can amend this rule") or "comex is hereby awarded X") but I can't remember anyone trying to change their name to intercept the rule in progress (or avoid it if it's a proposal-based punishment/reset).
I don't think it's the document-language of R1586 that enables/prevents this, because that language doesn't give any weight to whomever first has that name upon rule enaction. (It's slightly ironic, because that's why I used the the nomic nickname "Goethe" in the first place). Murphy, do you have any memory of such attempts from before my time? -G.
