Of course, then there's the fandoms that use /You instead. I was using the various filter checkboxes to drill down to a particular trope and fic length and then went into screen out pairings I didn't want, and there it was, in the top ten list. Who would even canonicize a tag like that, anyway? *sigh*

Also: just found the browser extension they probably mean you to use instead of icky manual search-and-replace that gasp, might result in you pirating some of their work. Change it once, and all Y/N ever will suddenly show up in your name on any webpage you view that includes it. (Which, LOL, would probably make any article you viewed that legitimately used Y/N for yes/no a rather interesting read ....)
