A Casual Vacancy J.K Rowling

A Casual Vacancy tells the story of a man named Stuart, nicknamed Fats, and his friend Andrew. together they use incredible hacking skills to hack into the Pagford Parish website, and manipulate the posts. They take Barry Fairbrothers account, and rename it "The_Ghost_Of_Barry_Fairbrother".  They use this account to eliminate applicants that they do not like. I think that this is important for the storyline, because, if other hackers like Suvinder go on the account, than they can eliminate people, so there is no chance to find the person who made the first injection on the site.
