I don't think she is the most hated, I just think most of her haters are quite vocal. The majority of tengaged stays out of major drama. Voting is open to everyone, so it's not just people voting who like her, but people voting her because they dislike who she is up against, voting her out of spite for mutual enemies, people who don't know her but liked her speech or picture, etc.
I don't think it was multis. Too my knowledge, Tara isn't a big multi user. I also skimmed though the comments when she was nominated and in the finals, and a lot of people were posting support.
