Reminder of who + why from Wiki:
BB1's Nick -
Nick attempted to influence the nominations of other housemates, infamously earning him the nickname: "Nasty Nick".
BB5's Kitten -
Repeatedly broke the rules. This ejection was different from a usual ejection as Kitten was ejected live in the style of an eviction (minus the crowd) instead of being asked by Big Brother to leave via the back door.
BB5's Emma -
After being highly involved in a physical argument, deemed "Fight Night", Emma was ejected due to fears she could spark another fight.
BB7's Dawn -
Confessed to setting up a code with her family prior to entering the House in order for her to recieve information from the outside world. She received a message saying that her sister was ill, which was a coded message meaning Dawn was receiving negative press on the outside world.
BB8's Emily -
Used a racially offensive word in reference to fellow housemate, Charley. Despite arguing she used it in a context that was not intentionally racist, Big Brother ejected Emily in the early hours of the next morning. Big Brother received complaints for her ejection as it seemed that Big Brother was attempting to redeem itself for the race row scandal of Celebrity Big Brother 5.
BB9's Alexandra -
Following complaints about her bullying and abusive behaviour towards other housemates, Big Brother ejected Alexandra for making, what appeared to be, gang threats to the other housemates and their families.
BB9's Dennis -
During Spitgate, Dennis spat in Mohamed's face, despite claiming that no spit ever left his mouth and hit Mohamed.
I dont think it matters with Dawn really, as she would have gone anyway, although to be fair on her she asked to leave before Big Brother booted her out so that was just them trying to make it look like she hadnt pulled the wool over their eyes by classing her as an ejection.
Id say Emma definitely! It was totally unfair how they singled her out in the argument and I also dont think she was the single cause of it. Should have all been just given a final warning those involved. And then also Emily, was a rushed decision that she was ejected early hours of the morning (couldnt wait 'til she got up

), and also she didnt say it in an offensive way anyway - shoudla just been a harsh warning!
