As for the multivoters, if you would browse for the comments in the FB Plug-in, you'll see that Kanade's voters are actually doing multivoting. Shana fans also did that. But more on Kanade.
Now, Shana has lost support from RailDex fans and got anti-voters from Pro-Kanade. She might also lose K-on fans because of her win against Azusa. Life must be so cruel for her.
Anti-Kanades don't care about her anymore, and will focus on Ruri (or less chance, Misaka) defeating her for 3rd spot. But, because of her win, I think some cunning Shana fans (like me,*evil giggle*) will do something about it. I love numbers.
My dream has been .... Ahhh... *eyes twinkling*
Go Shana! This must be the best chance for you to win the Tiara.
Let her sleep, though. 3 years in ISML, remaining active and on the best moe list. If Shana will win, she'll be one of those fallen Tiara holders and will stop rendering necklaces. If else she will not grab this Tiara, she will continue on doing it for ate least 3 to 5 more years. Let her , you know what I am planning... *wink, wink*
Nii-San: Seriously, I don't know them both. You can state which among them is stronger, and then I will decide my vote. *opens his laptop*
Otouto: Onee-chan, Kanade is more moe at her gif
(Me thinks something cunning)
M: I think I can also do that, even when she's moer. I can make my hair flip . It's always windy for me.
N: *looks at gif* Thinks she's so simple. But your bet is simple too. Look at the Nekomimi (referring to Azunyan) pic. That's cute.
O: I can spurt out water too. I always do that in our bathtub.
M: Yes, but... *giggles* Can you spurt out lava with your hands and wash yourself with lava?
O: Seriously, that's lava?
M: Yes! She did that on the anime!
N: You got my vote, li'l sis.
O: Count my vote in too, nii-san! I always dreamt of even touching lava!
M: *evil giggle*
Lol. One crazy convo.
