Clearly

Not so, good sir. Do you call me a liar? I would challenge you on the field of honor, had I any.

For what it's worth, I hadn't read the Rowling books when I first read MoR, and finding out who Quirrell was was actually somewhat of a shock. I'm the target audience for this rule, so far as any such exists, and I think it's pretty dumb.

Is anyone logging anecdotes? We've got one here!

I wouldn't just slap it on as a chapter title if I was the editor, but if you're reading this forum thread, certain things are assumed of you.

Okay. That's cool. So how do you feel about following politely asked and reasonable requests that cost you only quick trip to rot13.com and are enthusiastically enforced by at least a handful of trigger-happy registrants of karmic disapproval?

If said under-thumbers weren't in play, would you obey the request of the author?

What's your price?
