I'm not to worried about the FB hate because she has had it all season, especially after Stacey left. It hasn't made much of a difference yet.
I've voted more then I have ever voted since lasts nights episode and I'm not stopping!
There's also the issue that the tally board tells people who to vote for if they hate someone.
Where as say before if someone didn't want Estelle to win, they'd be splitting between Layla, Michael, Ben ect. Now they all know to go for Ben.
