It's a really, really simple rule, and people still manage to fuck it up! See example #2 from this year's noms: somebody trying to get Sid and Claude in under Pens RPF. Which, uh, Sid is one of literally 5 characters who have too many fics written about them to not qualify in the realm of hockey...and, at least in this reality, CLAUDE GIROUX HAS NEVER PLAYED FOR THE PENS. This should not be hard, people....
