Secret vote? The only place I know of where Iolol's name got mentioned negatively was in our own "Forum Post of the Day" about worst NPC names, and the forum post that accompanied it. Of course, there could have also been a "secret vote" somewhere else, and I don't remember Iolol drawing all that much ire-- the most hated names, if I recall, were Nutral the flight master and Haris Pilton.
And of course "Moi'bff Jill" ("my best friend forever, Jill") isn't that great a name either. Although I guess going the way of Corki (who got shipped off to live with the Night Elves) wouldn't have been that much fun, either.
